- Use the class MyArrayList to implement the interface MyList listed below using parallel streams and write a test program to test the methods. The class should be thread safe. interface MyList{ public void add(E x); public void add(List lst); public boolean forAll(Predicate pr); public boolean exists(Predicate pr); public long count(Predicate pr); public List map(Function fn); public List filter(Predicate pr); public List mapFilter(Function fn, Predicate pr); } class MyArrayList implements MyList { private ArrayList data = new ArrayList<>(); … }C++ Design a HashMap without using any built-in hash table libraries. Implement the MyHashMap class: MyHashMap() initializes the object with an empty map. void put(int key, int value) inserts a (key, value) pair into the HashMap. If the key already exists in the map, update the corresponding value. int get(int key) returns the value to which the specified key is mapped, or -1 if this map contains no mapping for the key. void remove(key) removes the key and its corresponding value if the map contains the mapping for the key. Example 1: Input ["MyHashMap", "put", "put", "get", "get", "put", "get", "remove", "get"] [[], [1, 1], [2, 2], [1], [3], [2, 1], [2], [2], [2]] Output [null, null, null, 1, -1, null, 1, null, -1]This question is in Java. We are required to map over some data and incement by 10. import.java.util.stream.Collectors; import.java.util.stream.Stream public class IncrementTheData implements Assignment {public Object solution(ArrayList<Integer> nums) { Stream.of(1,2,3,4,5,6) .map(not sure what would go in here) .collectors(Collectors.toList())return null;}} //So this is as far as I got with this question. The instructions are vague but I think I'm on the right track. Am I?
- In JAVA please Write a generic AddressBook<E extends Person> class that manages a collection ofPerson objects. The AddressBook class is a generic class limited to person objects. Forexample, once you instantiate an AdressBook of Student objects, you cannot add anyother type of person objects into that instance of address book.The AddressBook should have methods to add, delete, or search for a Person objects inthe address book.• The add method should add a person object to the address book. Make sure thatthe add method does not add duplicate person objects to the address book.• The delete method should remove the specified person object from the addressbook.• The search method that searches the address book for a specified person andreturns the list of persons matching the specified criteria. The search can be doneeither by first name, last name, or person id.Write an AddressBookTester class to test your class.Use java.util.Map, java.util.Set and given class Parition.java, write a Java method that receives a positive integer and prints all of its partitions. For example, if the input is 5, it prints the following seven lines, each representing one partition of integer 5 Please can you help with the following activity? Use java. util.Map, java. util.Set and given class Parition.java: import java.util.*;public class Partition implements Comparable<Partition> { /*represents a partition for int sum. * Example: * if sum = 14, * frequency can be { * 1:1, 3:1, 5:2} * which means 14 = 5 + 5 + 3 + 1 * */ public int sum; public String rep = ""; public TreeMap<Integer,Integer> frequencies; Partition(){//default constructor, parition for sum = 1 frequencies = new TreeMap<>(); this.sum = 1; frequencies.put(1, 1); } Partition(int sum){ frequencies = new TreeMap<>(); this.sum = sum; } public String toString(){…The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
- Write a Java program that prompts a user for vehicle data and stores it in a linked list, and then sorts the list in ascending order based on miles-per-gallon and writes the sorted data to a text file, you can follow these steps: Create a class named Vehicle with private fields: make (String), model (String), and milesPerGallon (double). Include getters and setters for these fields. Implement the Comparable interface for Vehicle class and override the compareTo() method to compare vehicles based on their milesPerGallon. Create a main class (for example, VehicleDriver.java) to handle user input and perform the necessary operations. Inside the main method, create a BufferedReader object for user input. Prompt the user to enter the number of vehicle data they want to enter and store it in a variable (for example, nVehicles). Use a loop to iterate nVehicles times and prompt the user to enter make, model, and miles per gallon for each vehicle. Create Vehicle objects using the input data…Add unit testing to the textanalyzer class. Please perform this task using JUnit. import java.util.ArrayList; import java.util.Collections; import java.util.Comparator; import java.util.HashMap; import java.util.List; import java.util.Map; import java.util.Set; import java.io.*; public class TextAnalyzer { public static void main(String[] args) throws Exception { String Word; URL poem = new URL("https://www.gutenberg.org/files/1065/1065-h/1065-h.htm"); BufferedReader in = new BufferedReader( new InputStreamReader(poem.openStream())); Map map = new HashMap(); while ((Word = in.readLine()) != null) { String[] words = Word.split("[\\s.;,?:!()\"]+"); for (String word : words) { word = word.trim(); if (word.length() > 0) { if (map.containsKey(word)) { map.put(word, map.get(word) + 1); } else { map.put(word, (int) 1L); } } } } // retrieving the map contents Set> set = map.entrySet(); // make an array list List> sortedList = new…Write a recursive instance method named findBad that takes no parameters and returns a reference to a Link. The result of calling findBad is a reference to the first link that has a value greater than the next link's value. If no such link exists return null. For example, for {5→6→7→3→2} it would return a reference to the third link ("7").
- JAVA Create a new class HashMapManipulation with a main method. Import the necessary classes from the java.util package, including the HashMap class. Create a HashMap object, named mapand use the put() method to add key-value pairs to the map. The keys are strings "A", "B", and "C", and the values are integers 1, 2, and 3 respectively. Use the size() method to print the size of the map. Use a for loop to print the key-value pairs in the map. The loop should iterate over the entries in the map using the entrySet() method, which will return a set of Map.Entry objects representing the key-value pairs in the map. The key and value of each entry are printed using the getKey() and getValue() methods, respectively. Use theget() method to get the value of key "A", and assigns it to a variable value. The value is then printed. Use the put() method to add a new key-value pair to the map. The key is "D" and the value is 4. The map is then printed again, to show the added key-value…JAVA I am trying to figure out how to connect the PaymentBatchProcessor Class (generic) to the Payment Class(interface).
