Similarities Between Edgar Allen Poes Life and His...

Similarities Between Edgar Allen Poes Life and His Literary Works In Edgar Allan Poes lifetime and today, critics think that there are striking similarities between what Poe lived and what he wrote. His melancholy, often-depressing stories are thought to reflect his feelings. There is truth to this, although his entire life was not miserable. In fact, in some of his poems, the good characters are modeled after him. Edgar Allan Poes writing was affected by many things in his life, including his turbulent childhood, his poverty, and his many tragic losses. In Poes childhood, he had five parents. His original mother and father Elizabeth Arnold and David Poe ,Jr.; John Allan and Fanny Allan who took him in†¦show more content†¦He would often quote Cervantes or Shakespeare and add that he was envious of their literary genius. At the tender age of fifteen, someone offered to publish a book of his works. Allan would not allow it though, as he was afraid of Poes ego swelling. Poe strived to excel in everything he did, swimming, long jump, running, and writing. This will to succeed showed up in his work later in life when he wrote constantly to keep up with the demand for his stories. Poe eventually broke away from Allan as a result of an argument between Allan and his second wife with Poe taking the wifes side. He did briefly reconnect with Allan to get his recommendation for West Point. Poe eventually purposely failed our of West Point by missing classes and lost touch with his father all together.(18) These tumultuous times had great highs and lows which greatly affected Poes later writings. Another aspect of Poes life, which greatly affected his writing, was his poverty. Silverman agrees saying that, poverty was a consistent thread throughout his entire life (except his time with the Allans).

Industries Was the Company Popularly Known †Myassignmenthelp.Com

Question: Discuss About The Industries The Company Popularly? Answer: Introduction Sam Snapshot is the owner of Snapshot industries. The industry was popular for making kitchen ware and gardening tools. Sam Snapshot had 200 employees in its company and they were working from 25 years in the same company. All the employees were expert in their own work. Each employee was assigned an individual work that added the value to their work. After the death of Sam, Jim overtook the company. He expanded the company by acquiring other companies and hired 400 more employees. He created a competitive environment in the company which was not compatible for the older employees and older employees started resigning and taking retirement due to which some problem arose in the production unit of the company. Consultants said that this is the problem of knowledge management. Knowledge Management is the process that helps in the sharing, gathering, creating and retrieval of the knowledge whenever it is necessary. Link between case study and knowledge management According to the case study the Sam Snapshot was the founder of Snapshot. The Snapshot was making commercial products in kitchenwares and gardening tools. There were only 200 employee earlier. The employees were working in Snapshot for 25 years. Each employee was having an individual role in the company which proved that the company valued each employee that was working with it. After the death of Sam Snapshot the Jim who was the grandson of Sam took over the company. The Company saw a major change after his death. New manufacturing and services were started by Jim. The employees increased to 600. The output of single product increased and multiple teams are formed for a single product. This resulted in increase of competition and also competition was increased as the rewards were given to the those who resulted in maximum output. Older employees started resigning and new employees were hired. Resigning was due to the increased competition in the company. But after some time there wa s a big problem in the company, as the teams were not able to do the work. All the papers and documents that were related to the problems scanned but the papers were indecipherable. This resulted to hire a consultant. The consultant linked the problem with knowledge management. Knowledge management is the collection, creation and spreading the knowledge within the company boundaries. Therefore, knowledge management is the doing whatever is needed to extract the knowledge from the resources. When the problem in the company arose, they looked on to the papers for solving the problem. But, the papers were impossible to read. Also, the old employee knew the solution of the problem which also resigned due to the companys environment. This helps the consultants realizing the problem that there were no information sources left in the company thats why they linked the problem with knowledge management. Snapshot industries and types of knowledge Knowledge Knowledge is linked with data and information. Knowledge is acquired by an individual with the experience and time, which comes to individual from seeing the external and the internal environment behavior. Therefore, knowledge can be explained as the mixture of values, experience, information and expert views. In an organization the knowledge becomes the daily practice and is embedded in the organization (Robertson, 2017). Specific type of knowledge Specific type of knowledge is the knowledge that is possessed by the limited numbers of persons in the organization. It is the knowledge related to a specific technical task or a deep knowledge regarding the specific area. This kind of knowledge requires a specific technical training or an experience to possess this knowledge. Therefore a specific knowledge pertains to a company that have different units with a specific number of tasks. The Snapshot has the specific kind of knowledge in it. It has the employees that do their individual work and do not interfere in others work. The employees were working there from last 25 years that why they were well experienced in their work and were experts in their tasks (Baqir, 2004). Strategic knowledge and its elements Strategic knowledge is the knowledge that is used to gain competitive advantage. The strategies are prepared in this highly competitive world so that advantage can be gained out for the success of the company. This type of knowledge gives an organization a long term advantage. This advantage is useful in the success of the company (Sarawanawong, 2009). A comprehensive knowledge regarding the process, production and management are the basic elements of strategic knowledge. The process indicates how the work is done in the company. It is related with the how the one to one process is one and initiated. Production is the main part where the products are formed. There are various processes in between the production of the desired product and the third element is management how to manage the working, how to deliver the product and how to make profit is the main work of the management team. Therefore, these are the main elements of strategic knowledge (Hariharan, 2015). Resignation and retirement as a problem In Snapshot the resignations and retirements occurred due to the competitive environment that was created by Jim in the company. The older employees that were about 25 years old were not compatible with the competitive environment. These employees were working in the Snapshot and each was assigned an individual work. After 25 years they were experts in their work. They know well how to solve any problem during the process. But after the competitive environment they started leaving the job. This was noted as a problem for the organization as there were no records available regarding the working process of each employee. The records were not maintained electronically. There were some records on paper which were not in a position to read. Therefore, no written records of the process and no experts that were left in the company created the problems in the working process of Snapshot. Even no new employee knew how to tackle the problem that arose during the work. Therefore, this made the problem more complex. And the experts who were working and found no time to explain the process as some of them were busy at their own work and some were not able to explain (Ranjan Khalil, 2007). Therefore, after their resignations the company work was affected due to which the cost of the product was increased and the production was low. These problems were created due to the resignations and retirements. Solution to the problem The problem was created due to the retirements and resignations. Firstly the solution to this problem was to respect each and every employee of the company. As they are the assets to the company. Only the employee knows the information and knowledge about the company. Therefore, talented employees performance should be regarded and appraisal and some additional benefits must be given to them so they do not resign. As due to the resignations and retirements, the company should also value the information the person has. Secondly the company should implement knowledge management (Bhattacharya Chaudhury, 2004). This will help the company to preserve the important information and knowledge regarding the companys process of working. It will also help the company realize the real assets of the company. This will help in a way that if some expert leaves the company or resigns, the work does not get affected. Also, knowledge management helps in the learning process of each employee. It will help in the training programs for each employee by which each employee sees his or her growth. This will lead to the employee satisfaction. Also, knowledge management will help in the growth of the company as an employee growth directly relates to the companys growth. Also, effectiveness, efficiency can be increased by incorporating knowledge management (Idayu, 2011). Consultants concern over leadership Consultants were concerned over the leadership because the leader is the main person who gives his vision for the successful running of the company. The leaders make decisions regarding any problem and help in finding the solution to that problem. Effective decision by the leader can help in solving the problem efficiently. Leaders also influence the employee behavior in several ways. A good leader knows how to make his or her employee satisfied and know the real value of his employee (Ward, 2017). Also, the leader does the work of motivation and guiding of the employee. Consultants were concerned over leader behavior as due to the new leader of the organization that is Jim, he was not able to handle the situation of retirements and resignations. Also, the work in production was affected due to these resignations. He was not able to motivate or guide any of the employees. Old as well as new employees was resigning due to the environment of the company. Leaders should listen to the employees and help them to share their vision with another employee. But Jim has created such an environment so that there was no communication between the employees. Therefore, no communication between the employees lead to the communication gap and there was no transfer of knowledge between the employees of the company. After evaluating this, consultants were concerned about the leadership. Effects of Jims leadership Earlier, the work was not done in the competitive manner. Each individual earlier was assigned a different work to do. Each employee was an expert in his or her work. But after Jim undertook the business, different teams were performing the similar work which increased the output of a single product. This also resulted in the increase in the competition level in the organization. Due to the increase in the competition level the stress on the employees was increased which resulted in the mis-happenings. Some employees that were working from a lot of time, resigned due to increase in the stress level (Hovland, 2003). Also, a new way of centralized system was installed in the company by which the employee has to submit their working times, their leaves and their supervisory records online. This also stressed the older employees as they were not compatible with the computer systems and were doing all the things manually on paper. This made them to learn even they did not know how to use the mouse. Therefore, these things stressed out the employees. Jim hired new employees, but they also resigned as they say that the product working information was not revealed to them. This made them to think about their growth in the company (Agrawal, 2013). Therefore, the new employees also resigned and did not see the compatibility between the old employees and them. Therefore the effects of Jim leadership were as follows. Competitive working environment in the organization Working on electronic systems. Problems occurred during the production process Stress on employees Resignations and retirements of employees New hirings of the employees Increase in the cost of the product. Ways by which Jim could improve his practices Jim could improve his practices by giving value to his employee. He should know the employees are the assets of the organization. By making them feel special in the organization can add value to the employee. This helps in the effective and efficient working of the employee. By giving regard to the employee they consider the organization's importance. Each leader should know that the talented and expert employees are the real assets of the company. Neither the machinery or the tools are the assets of the company. Therefore, by giving importance to each employee the problem can be solved up to some extent (Wang Wang, 2008). Also a problem in the company arose due to the no information regarding the production process of the company. Therefore, the problem related to the transfer of the information should be solved and knowledge management should be implemented in a way that proper communication of the knowledge among the employees should be done (Dowling, et al., 2011). Knowledge management implication areas Knowledge management can be applied to the production, employees and processes. From the production point of view, knowledge management adds value to the products. This impact of added value comes from the knowledge. It helps in providing added value to the earlier products, and also help in the innovation of new products. Therefore, snapshot can create new products and can add value to the older products with the help of knowledge management. Secondly, knowledge management can be applied to the employees means employees have a greater impact of knowledge management (Jasimuddin, 2006). Knowledge management helps in the employees learning by providing training and through the transfer of information within the company from one employee to another. From this employee see the growth of knowledge in the company. Growth helps in the increase in the efficiency and effectiveness of the work of the employee through the employee satisfaction. Thirdly, the process of working has a greater impa ct of knowledge management. Effectiveness, efficiency and innovation can be developed with the help of knowledge management. The best decision helps in the effectiveness of the work. And better decision is taken with the help of proper knowledge. Also, process efficiency can be increased with the help of knowledge management. Efficiency can be increased by doing the work quickly and in low cost. Innovative work can be done with the help of knowledge management by applying good knowledge (Jalalimanesh, 2014). Therefore, in production the knowledge management adds value to the product. In employees, it helps in learning and growth and in the process, it helps in the increase of effectiveness, efficiency and innovation. Knowledge management as a strategy. Why? Knowledge management is the strategy for snapshot industries as the problem in the Snapshot arose due to the resign and retirements. Also, the problem arose due to the key persons are not there in the teams and the working in the production was having the problem. There were not any information regarding the problem solution. There were some information but that information was indecipherable. Also, the experts of the work which were older employees left the job. And due to excess of competition within the company the transfer of information from these older employees did not take place. Therefore, Jim found the problem panicking. Knowledge management was the strategy to solve the problem. Knowledge management helps in maintaining the information regarding the workflow and the processes (Omotayo, 2015). The information will be stored in a way that it can be transferred to each employee in the company and also it can be retrieved whenever needed. Therefore, this strategy can help in s olving the problem of Snapshot. Also, the strategy will help in making the effective and efficient work. Also, it helps in recognizing the real assets of the company that are the employees which are not valued later by the Snapshot when Jim took over the company. Knowledge management and Solution to the problem of Snapshot Yes, knowledge management can solve the problem to some extent. But not all the problems in the company can be solved with knowledge management. The company or the leader should realize the importance of the older staff and should realize that the employee are very important for the proper running of the company. Information and knowledge can be collected and gathered, but can only be implemented by the employees. So the employees should be valued by the company (Alavi Leidner, 2001). Problem in the snapshot industries arose due to the leaving of the older employees who were expert in their work. Theses employee was satisfied during the leadership of Sam Sanpshot. But, after Jim overtook the company he created pressure on the employees and they started leaving the company. Therefore, the problems arose at the production unit in the company. Information regarding the problems was searched but there was no information on the company. Therefore, knowledge management was not implemented in the company and therefore no transfer of information took place during earlier times. But, during earlier times each employee was assigned a different task which adds value to them. Therefore, the working was going in a proper manner. But, when Jim overtook the company the working scenario changed, but due to lack of knowledge transfer between the employees the problem arose. This can be solved with the help of knowledge management, which helps in the collection and retrieval of kno wledge whenever needed. Also, it helps the new employees to know regarding the working process of the company (Cummings, et al., 2013). Conclusion Therefore, it can be concluded that Snapshot industries should implement knowledge management in the company. It will help in the collection, storing and retrieval of the knowledge whenever it is necessary. Also, the Snapshot industries should realize the importance of the employees. This will help in the talent to stay in the company. Knowledge management will help snapshot to realize the real assets of the organization. Also, to make innovative products Knowledge management is useful. Effective and efficient work is also done with the help of knowledge management. Effective and efficient work will help in adding an advantage to the workflow. Also, it will help the company to gain competitive advantage which will help in companys overall growth.

EventObject class is the highest-level class in the event-delegation class hierarchy. |   | | | Q:| What is the Collection interface? | A:| The Collection interface provides support for the implementation of a mathematical bag an unordered collection of objects that may contain duplicates. |   | | | Q:| What is the Set interface? | A:| The Set interface provides methods for accessing the elements of a finite mathematical set. Sets do not allow duplicate elements. |   | | | Q:| What is the typical use of Hashtable? | A:| Whenever a program wants to store a key value pair, one can use Hashtable. |   | | | Q:| I am trying to store an object using a key in a Hashtable. And some other object already exists in that location, then what will happen? The existing object will be overwritten? Or the new object will be stored elsewhere? | A:| The existing object will be overwritten and thus it will be lost. |   | | | Q:| What is the difference between the size and capacity of a Vector? | A:| The size is the number of elements actually stored in the vector, while capacity is the maximum number of elements it can store at a given instance of time.   | | | Q:| Can a vector contain heterogenous objects? | A:| Yes a Vector can contain heterogenous objects. Because a Vector stores everything in terms of Object. |   | | | Q:| Can a ArrayList contain heterogenous objects? | A:| Yes a ArrayList can contain heterogenous objects. Because a ArrayList stores everything in terms of Object. |   | | | Q:| What is an enumeration? | A:| An enumeration is an interface containing methods for accessing the underlying data structure from which the enumeration is obtained.

It allows sequential access to all the elements stored in the collection. |   | | | Q:| Considering the basic properties of Vector and ArrayList, where will you use Vector and where will you use ArrayList? | A:| The basic difference between a Vector and an ArrayList is that, vector is synchronized while ArrayList is not. Thus whenever there is a possibility of multiple threads accessing the same instance, one should use Vector. While if not multiple threads are going to access the same instance then use ArrayList. Non synchronized data structure will give better performance than the synchronized one. |   | | | Q:| Can a vector contain heterogenous objects? | A:| Yes a Vector can contain heterogenous objects. Because a Vector stores everything in terms of Object. |   | Java Collections Interview QuestionsWhat is HashMap and Map? Map is Interface and Hashmap is class that implements this interface. What is the significance of ListIterator? OrWhat is the difference b/w Iterator and ListIterator? Iterator :  Enables you to cycle through a collection in the forward direction only, for obtaining or removing elementsListIterator :  It extends Iterator, allow bidirectional traversal of list and the modification of elementsDifference between HashMap and HashTable? Can we make hashmap synchronized? 1. The HashMap class is roughly equivalent to Hashtable, except that it is unsynchronized and permits nulls. (HashMap  allows null values as key and value whereas Hashtable doesn’t allow nulls). 2. HashMap does not guarantee that the order of the map will remain constant over time. 3. HashMap is non synchronized whereas Hashtable is synchronized. . Iterator in the HashMap is fail-safe while the enumerator for the Hashtable isnt. Note on Some Important Terms 1)Synchronized means only one thread can modify a hash table at one point of time. Basically, it means that any thread before performing an update on a hashtable will have to acquire a lock on the object while others will wait for lock to be released. 2)Fail-safe is relevant from the context of iterators. If an iterator has been created on a collection object and some other thread tries to modify the collection object structurally†, a concurrent modification exception will be thrown. It is possible for other threads though to invoke set method since it doesn’t modify the collection structurally†. However, if prior to calling set, the collection has been modified structurally, IllegalArgumentException will be thrown. HashMap can be synchronized byMap m = Collections. synchronizeMap(hashMap);What is the difference between set and list? A Set stores elements in an unordered way and does not contain duplicate elements, whereas a list stores elements in an ordered way but may contain duplicate elements. Difference between Vector and ArrayList? What is the Vector class? Vector is synchronized whereas ArrayList is not. The Vector class provides the capability to implement a growable array of objects. ArrayList and Vector class both implement the List interface. Both classes are implemented using dynamically resizable arrays, providing fast random access and fast traversal. In vector the data is retrieved using the elementAt() method while in ArrayList, it is done using the get() method. ArrayList has no default size while vector has a default size of 10. when you want programs to run in multithreading environment then use concept of vector because it is synchronized. But ArrayList is not synchronized so, avoid use of it in a multithreading environment. What is an Iterator interface? Is Iterator a Class or Interface? What is its use? The Iterator is an interface, used to traverse through the elements of a Collection. It is not advisable to modify the collection itself while traversing an Iterator. What is the Collections API? The Collections API is a set of classes and interfaces that support operations on collections of objects. Example of classes: HashSet, HashMap, ArrayList, LinkedList, TreeSet and TreeMap. Example of interfaces: Collection, Set, List and Map. What is the List interface? The List interface provides support for ordered collections of objects. How can we access elements of a collection? We can access the elements of a collection using the following ways: 1. Every collection object has get(index) method to get the element of the object. This method will return Object. 2. Collection provide Enumeration or Iterator object so that we can get the objects of a collection one by one. What is the Set interface? The Set interface provides methods for accessing the elements of a finite mathematical set. Sets do not allow duplicate elements. What’s the difference between a queue and a stack? Stack is a data structure that is based on last-in-first-out rule (LIFO), while queues are based on First-in-first-out (FIFO) rule. What is the Map interface? The Map interface is used associate keys with values. What is the Properties class? The properties class is a subclass of Hashtable that can be read from or written to a stream. It also provides the capability to specify a set of default values to be used. Which implementation of the List interface provides for the fastest insertion of a new element into the middle of the list? a. Vector   b. ArrayList . LinkedList d. None of the aboveArrayList and Vector both use an array to store the elements of the list. When an element is inserted into the middle of the list the elements that follow the insertion point must be shifted to make room for the new element. The LinkedList is implemented using a doubly linked list; an insertion requires only the updating of the links at t he point of insertion. Therefore, the LinkedList allows for fast insertions and deletions. How can we use hashset in collection interface? This class implements the set interface, backed by a hash table (actually a HashMap instance). It makes no guarantees as to the iteration order of the set; in particular, it does not guarantee that the order will remain constant over time. This class permits the Null element. This class offers constant time performance for the basic operations (add, remove, contains and size), assuming the hash function disperses the elements properly among the buckets. What are differences between Enumeration, ArrayList, Hashtable and Collections and Collection? Enumeration: It is series of elements. It can be use to enumerate through the elements of a vector, keys or values of a hashtable. You can not remove elements from Enumeration. ArrayList:  It is re-sizable array implementation. Belongs to List group in collection. It permits all elements, including null. It is not thread -safe. Hashtable:  It maps key to value. You can use non-null value for key or value. It is part of group Map in collection. Collections:  It implements Polymorphic algorithms which operate on collections. Collection:  It is the root interface in the collection hierarchy. What is difference between array ; arraylist? An ArrayList is resizable, where as, an array is not. ArrayList is a part of the Collection Framework. We can store any type of objects, and we can deal with only objects. It is growable. Array is collection of similar data items. We can have array of primitives or objects. It is of fixed size. We can have multi dimensional arrays. Array:  can store primitive  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ArrayList:  Stores object onlyArray:  fix size  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ArrayList:  resizableArray:  can have multi dimensionalArray:  lang   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ArrayList:  Collection frameworkCan you limit the initial capacity of vector in java? Yes you can limit the initial capacity. We can construct an empty vector with specified initial capacitypublic vector(int initialcapacity)What method should the key class of Hashmap override? The methods to override are equals() and hashCode(). What is the difference between Enumeration and Iterator? The functionality of Enumeration interface is duplicated by the Iterator interface. Iterator has a remove() method while Enumeration doesnt. Enumeration acts as Read-only interface, because it has the methods only to traverse and fetch the objects, where as using Iterator we can manipulate the objects also like adding and removing the objects. So Enumeration is used when ever we want to make Collection objects as Read-only. Collections Interview Questions| Q1) What is difference between ArrayList and vector? Ans: )1) Synchronization ArrayList is not thread-safe whereas Vector is thread-safe. In Vector class each method like add(), get(int i) is surrounded with a synchronized block and thus making Vector class thread-safe. 2) Data growth Internally, both the ArrayList and Vector hold onto their contents using an Array. When an element is inserted into an ArrayList or a Vector, the object will need to expand its internal array if it runs out of room. A Vector defaults to doubling the size of its array, while the ArrayList increases its array size by 50 percent. | Q2) How can Arraylist be synchronized without using Vector? Ans) Arraylist can be synchronized using:Collection. synchronizedList(List list)Other collections can be synchronized:Collection. synchronizedMap(Map map)Collection. synchronizedCollection(Collection c)| Q3) If an Employee class is present and its objects are added in an arrayList. Now I want the list to be sorted on the basis of the employeeID of Employee class. What are the steps? Ans) 1) Implement Comparable interface for the Employee class and override the compareTo(Object obj) method in which compare the employeeID2) Now call Collections. sort() method and pass list as an argument. Now consider that Employee class is a jar file. 1) Since Comparable interface cannot be implemented, create Comparator and override the compare(Object obj, Object obj1) method . 2) Call Collections. sort() on the list and pass comparator as an argument. | Q4)What is difference between HashMap and HashTable? Ans) Both collections implements Map. Both collections store value as key-value pairs. The key differences between the two are1. Hashmap is not synchronized in nature but hshtable is. 2. Another difference is that iterator in the HashMap is fail-safe while the enumerator for the Hashtable isnt. Fail-safe   aâ‚ ¬? if the Hashtable is structurally modified at any time after the iterator is created, in any way except through the iterators own remove method, the iterator will throw a ConcurrentModificationExceptionaâ‚ ¬? 3. HashMap permits null values and only one null key, while Hashtable doesnt allow key or value as null. | Q5) What are the classes implementing List interface? Ans) There are three classes that implement List interface: 1)  ArrayList  : It is a resizable array implementation. The size of the ArrayList can be increased dynamically also operations like add,remove and get can be formed once the object is created. It also ensures that the data is retrieved in the manner it was stored. The ArrayList is not thread-safe. 2)  Vector: It is thread-safe implementation of ArrayList. The methods are wrapped around a synchronized block. 3)  LinkedList: the LinkedList also implements Queue interface and provide FIFO(First In First Out) operation for add operation. It is faster if than ArrayList if it performs insertion and deletion of elements from the middle of a list. | Q6) Which all classes implement Set interface? Ans) A Set is a collection that contains no duplicate elements. More formally, sets contain no pair of elements e1 and e2 such that e1. equals(e2), and at most one null element. HashSet,SortedSet and TreeSet  are the commnly used class which implements Set interface. SortedSet   It is an interface which extends Set. A the name suggest , the interface allows the data to be iterated in the ascending order or sorted on the basis of Comparator or Comparable interface. All elements inserted into the interface must implement Comparable or Comparator interface. TreeSet   It is the implementation of SortedSet interface. This implementation provides guaranteed log(n) time cost for the basic operations (add, remove and contains). The class is not synchronized. HashSet:  This class implements the Set interface, backed by a hash table (actually a HashMap instance). It makes no guarantees as to the iteration order of the set; in particular, it does not guarantee that the order will remain constant over time. This class permits the null element. This class offers constant time performance for the basic operations (add, remove, contains and size), assuming the hash function disperses the elements properly among the buckets| Q7) What is  difference  between List and a Set? Ans) 1) List can contain duplicate values but Set doesnt allow. Set allows only to unique elements. 2) List allows retrieval of data to be in same order in the way it is inserted but Set doesnt ensures the sequence in which data can be retrieved. (Except HashSet)| Q8) What is difference between Arrays and ArrayList ? Ans) Arrays are created of fix size whereas ArrayList is of not fix size. It means that once array is declared as : 1. int [] intArray= new int[6]; 2. intArray[7]  Ã‚   // will give ArraysOutOfBoundException. Also the size of array cannot be incremented or decremented. But with arrayList the size is variable. 2. Once the array is created elements cannot be added or deleted from it. But with ArrayList the elements can be added and deleted at runtime. List list = new ArrayList(); list. add(1); list. add(3); list. remove(0) // will remove the element from the 1st location. 3. ArrayList is one dimensional but array can be multidimensional. nt[][][] intArray= new int[3][2][1];  Ã‚   // 3 dimensional array  Ã‚  Ã‚  Ã‚   4. To create an array the size should be known or initalized to some value. If not initialized carefully there could me memory wastage. But arrayList is all about dynamic creation and there is no wastage of memory. | Q9) When to use ArrayList or LinkedList ? Ans)   Adding new elements is pretty fast for either type of list. For the ArrayL ist, doing   random lookup using get is fast, but for LinkedList, its slow. Its slow because theres no efficient way to index into the middle of a linked list. When removing elements, using ArrayList is slow. This is because all remaining elements in the underlying array of Object instances must be shifted down for each remove operation. But here LinkedList is fast, because deletion can be done simply by changing a couple of links. So an ArrayList works best for cases where youre doing random access on the list, and a LinkedList works better if youre doing a lot of editing in the middle of the list. | Q10) Consider a scenario. If an ArrayList has to be iterate to read data only, what are the possible ways and which is the fastest? Ans) It can be done in two ways, using for loop or using iterator of ArrayList. The first option is faster than using iterator. Because value stored in arraylist is indexed access. So while accessing the value is accessed directly as per the index. | Q11) Now another question with respect to above question is if accessing through iterator is slow then why do we need it and when to use it. Ans) For loop does not allow the updation in the array(add or remove operation) inside the loop whereas Iterator does. Also Iterator can be used where there is no clue what type of collections will be used because all collections have iterator. | Q12) Which design pattern Iterator follows? Ans) It follows Iterator design pattern. Iterator Pattern is a type of behavioral pattern. The Iterator pattern is one, which allows you to navigate through a collection of data using a common interface without knowing about the underlying implementation. Iterator should be implemented as an interface. This allows the user to implement it anyway its easier for him/her to return data. The benefits of Iterator are about their strength to provide a common interface for iterating through collections without bothering about underlying implementation. Example of Iteration design pattern Enumeration The class java. util. Enumeration is an example of the Iterator pattern. It represents and abstract means of iterating over a collection of elements in some sequential order without the client having to know the representation of the collection being iterated over. It can be used to provide a uniform interface for traversing collections of all kinds. | Q12) Is it better to have a HashMap with large number of records or n number of small hashMaps? Ans) It depends on the different scenario one is working on: 1) If the objects in the hashMap are same then there is no point in having different hashmap as the traverse time in a hashmap is invariant to the size of the Map. ) If the objects are of different type like one of Person class , other of Animal class etc then also one can have single hashmap but different hashmap would score over it as it would have better readability. | Q13) Why is it preferred to declare: ListString list = new ArrayListString(); instead of ArrayListString = new ArrayListString();Ans) It is preferred because: 1. If later on code needs to be changed from ArrayList to Vector then only at the declaration place we can do that. 2. The most important one – If a function is declared such that it takes list. E. g void showDetails(List list); When the parameter is declared as List to the function it can be called by passing any subclass of List like ArrayList,Vector,LinkedList making the function more flexible| Q14) What is difference between iterator access and index access? Ans) Index based access allow access of the element directly on the basis of index. The cursor of the datastructure can directly goto the n location and get the element. It doesnot traverse through n-1 elements. In Iterator based access, the cursor has to traverse through each element to get the desired element. So to reach the nth element it need to traverse through n-1 elements. Insertion,updation or deletion will be faster for iterator based access if the operations are performed on elements present in between the datastructure. Insertion,updation or deletion will be faster for index based access if the operations are performed on elements present at last of the datastructure. Traversal or search in index based datastructure is faster. ArrayList is index access and LinkedList is iterator access. | Q15) How to sort list in reverse order? Ans) To sort the elements of the List in the reverse natural order of the strings, get a reverse Comparator from the Collections class with reverseOrder(). Then, pass the reverse Comparator to the sort() method. List list = new ArrayList();Comparator comp = Collections. reverseOrder();Collections. sort(list, comp)| Q16) Can a null element added to a Treeset or HashSet? Ans) A null element can be added only if the set contains one element because when a second element is added then as per set defination a check is made to check duplicate value and comparison with null element will throw NullPointerException. HashSet is based on hashMap and can contain null element. | Q17) How to sort list of strings case insensitive? Ans) using Collections. sort(list, String. CASE_INSENSITIVE_ORDER);| Q18) How to make a List (ArrayList,Vector,LinkedList) read only? Ans) A list implemenation can be made read only using  Collections. unmodifiableList(list). This method returns a new list. If a user tries to perform add operation on the new list; UnSupportedOperationException is thrown. | Q19) What is ConcurrentHashMap? Ans) A concurrentHashMap is thread-safe implementation of Map interface. In this class put and remove method are synchronized but not get method. This class is different from Hashtable in terms of locking; it means that hashtable use object level lock but this class uses bucket level lock thus having better performance. | Q20) Which is faster to iterate LinkedHashSet or LinkedList? Ans) LinkedList. | Q21) Which data structure HashSet implementsAns) HashSet implements hashmap internally to store the data. The data passed to hashset is stored as key in hashmap with null as value. Q22) Arrange in the order of speed HashMap,HashTable, Collections. synchronizedMap,concurrentHashmapAns) HashMap is fastest, ConcurrentHashMap,Collections. synchronizedMap,HashTable. | Q23) What is identityHashMap? Ans) The IdentityHashMap uses == for equality checking instead of equals(). This can be used for both performance reasons, if you know that two different elements will never be equals and for preventing spoofing, where an object tries to imitate another. | Q24) What is WeakHashMap? Ans) A hashtable-based Map implementation with weak keys. An entry in a WeakHashMap will automatically be removed when its key is no longer in ordinary use. More precisely, the presence of a mapping for a given key will not prevent the key from being discarded by the garbage collector, that is, made finalizable, finalized, and then reclaimed. When a key has been discarded its entry is effectively removed from the map, so this class behaves somewhat differently than other Map implementations. QUESTIONS:1. You need to insert huge amount of objects and randomly delete them one by one. Which Collection data structure is best pet? Obviously, LinkedList. 2. What goes wrong if the HashMap key has same hashCode value? It leads to ‘Collision’ wherein all the values are stored in same bucket. Hence, the searching time increases quad radically. 3. If hashCode() method is overridden but equals() is not, for the class ‘A’, then what may go wrong if you use this class as a key in HashMap? Left to Readers. 4. How will you remove duplicate element from a List? Add the List elements to Set. Duplicates will be removed. 5. How will you synchronize a Collection class dynamically? Use the utility method  . |   | | |   | |
