- Write an application in java language using a hash table that finds all the pairs of two integers within the below array that add up to 12. Array = {4,9,6,13,5,3,2,8}In JAVA, use a HashMap to count and store the frequency counts for all the words from a large text document. Using file util, please. Then, display the contents of this HashMap with words and frequency count. Next, please create a set view of the Map and store the contents in an array. Sort this array based on key value and display it. Finally, sort the array in decreasing order by frequency and display it as well. Please label your explanation in the code Thank youObjective: This activity has the purpose of helping students to design proper hashing strategies. (Objective 3). Students Instructions: After studying this module, write the answer to the following programming assignments in a text file and submit them as an attached Word doc or PDF through the provided link in Blackboard. The deadline for submitting this assignment is indicated on "Tools", which is located in "Calendar" in the "Blackboard" platform. You will have two (2) attempt to send your answers by Assignment link before the deadline and the last submission would be considered as your final solution. This exercise has Implement a dictionary by using hashing and separate chaining. Question:
- Which of the following statements about ArrayLists is false? A running program can determine the size of an ArrayList. O You can get an item from a specified index in an ArrayList. O You can add a new item to the end of an ArrayList. O Once an ArrayList is created, its size cannot be changed.Create an array called array in bash with three elements in it, a hashmap /dict / associative array called hash with three elements in it, and a string variable called str with at least 15 characters where one of those characters is duplicated twice (i.e., in the string at least 3 times).Write code to create three instances of a HashMap class. Give two the same, and the third different data. Compare the objects and state the result
- you will create a spell checker. The program will take three command line arguments: number of words in the dictionary, a dictionary file name, and a text file name. The program will first create a hash table. The number buckets of the hash table should be about twice the number of words in the dictionary. Then, it will read the dictionary from the file, insert the words into the hash table, and report collision statistics. After reading the dictionary, the spelling checker will read a list of words from a text file. Each word will be looked up in the dictionary. If it is incorrect, it will be written to the standard output together with a list of suggested corrections. The algorithm for generating corrections is given below. Hash Table The hash table programs, QuadraticProbing.h and QuadraticProbing.cpp, are posted on Canvas. The programs use quadratic probing to deal with collisions. You should carefully study these programs and make some changes to collect the required statistics.…you will create a spell checker.

- Retrieving a value using its associated key can be accomplished using anindexer, which works just like an indexer for an array. A key is passed in asthe index value, and the value associated with the key is returned, unless thekey doesn’t exist, in which a null is returned.Write short code segment demonstrates how this technique works:In this assignment, you will compare the performance of ArrayList and LinkedList. More specifically, your program should measure the time to “get” and “insert” an element in an ArrayList and a LinkedList.You program should 1. Initializei. create an ArrayList of Integers and populate it with 100,000 random numbersii. create a LinkedList of Integers and populate it with 100,000 random numbers2. Measure and print the total time it takes to i. get 100,000 numbers at random positions from the ArrayList 3. Measure and print the total time it takes to i. get 100,000 numbers at random positions from the LinkedList 4. Measure and print the total time it takes to i. insert 100,000 numbers in the beginning of the ArrayList 5. Measure and print the total time it takes to i. insert 100,000 numbers in the beginning of the LinkedList 6. You must print the time in milliseconds (1 millisecond is 1/1000000 second).A sample run will be like this:Time for get in ArrayList(ms): 1Time for get in…In JAVA, use a HashMap to count and store the frequency counts for all the words from a large text document. Then, display the contents of this HashMap with given words and their frequency in the document. Next, please create a set view of the Map and store the contents in an array. Sort this array based on key value and display it. Finally, sort the array in decreasing order by frequency and display it.
