- Provide a different implementation of ChoiceQuestion. Instead of storing the choices in an array list, the addChoice method should add the choice to the question text. For this purpose, an addLine method has been added to the Question class. Use the following files: Question.java /** A question with a text and an answer.*/public class Question{ private String text; private String answer; /** Constructs a question with empty text and empty answer. */ public Question() { text = ""; answer = ""; } /** Sets the answer for this question. @param correctResponse the answer */ public void setAnswer(String correctResponse) { answer = correctResponse; } /** Checks a given response for correctness. @param response the response to check @return true if the response was correct, false otherwise */ public boolean checkAnswer(String response) { return response.equals(answer); } /** Add a line of text to…Given that an ArrayList of Strings named friendList has already been created and names have already been inserted, write the statement necessary to change the name "Tyler", stored at index 8, to "Bud". This is needed in JavaThis is needed in Java Given an existing ArrayList named friendList, find the first index of a friend named Sasha and store it in a new variable named index.
- How do I add several objects to an ArrayList in JAVA using a loop?Write a program in which you create an object of type ArrayList named BZ and then add 3 elements in this object and then copy the elements of the object in another object QZ and then cancel the elements of the object BZ and then write the necessary print statements to show it? in javaIn java Write a method public static ArrayList<Integer> append(ArrayList<Integer> a, ArrayList<Integer> b) that appends one array list after another. Ex: a = 1 2 3 4 5, b = 6 7 8 9 10 then append returns 1 2 3 4 5 6 7 8 9 10
- java Write a method that takes rows and columns as a parameter, and returns a 2D array of the designated size, filled with empty Strings. I currently have public static String[][] createArray(int row, int col) { String[][]arr=new String[row][col]; return arr; } but it returns the 2d array filled with null?Please create a program in Java which will include a method that will merge sort an array of strings and not ints.What is the output of the following Java code? ArrayList<String> names = new ArrayList<>(); names.add("James"); names.add("Mary"); names.add("Henry"); names.add("George"); names.add("Mary"); names.add("John"); names.add("Zachery"); Set names_wo_duplicate = new HashSet(names); Iterator set_val = names_wo_duplicate.iterator(); while(set_val.hasNext()) System.out.print(set_val.next() + ", "); Group of answer choices James, George, John, Zachery, Henry, Mary James, Mary, Henry, George, John, Zachery None of the above Code does not compile because of syntax errors
- Write a Program in Java programming: Support you have an ArrayList containing random integers. These integers can be any number, and each integer can appear more than once. For example, [2, 19, 21, 19, 21, 1, 3, 3, 6, 21, .....] Your job is to write a method called findEvenFrequentNumbers(ArrayList<Integer> list) that returns an ArrayList which has all the numbers appears in even frequency and in increasing order. e.g. list = [2, 19, 21, 19, 21, 1, 3, 3, 6, 21], should return [3, 19] list = [3, 3, 3, 1, 2, 2, 2, 2, 2], should return [] list = [1, 1, 1, 1, 1], should return [1] Note that you need to provide a class with the main function and also the imports.In java, Write a method void popMult(int k) for the ArrayBoundedStack class which will pop k items from this. Throw a StackUnderflowException and don't pop anything if there are fewer than k items on this. This is a method of the ArrayBoundedStack class. DO NOT USE ANY OTHER METHODS OF THE ARRAYBOUNDEDSTACK CLASS.In java, Implement a method that removes all duplicates. Keep the first instance of the element but remove all subsequent duplicate elements.public void removeDuplicates() see the picture for the right output. Given files: Demo6.java public class Demo6 { public static void main(String[] args) { MyLinkedList<String> list = new MyLinkedList<>(); TestBench.addToList(list); TestBench.addToList(list); TestBench.addToList(list); TestBench.addToList(list); for (int x = 0; x < list.size(); x += 1 + x/3) { System.out.println("Removing element at index: " + x); list.remove(x); } System.out.println("Result"); System.out.println(list); System.out.println("Shuffling"); list.shuffle(7777); System.out.println(list); System.out.println("Removing duplicates (keeping first instance)"); list.removeDuplicates(); System.out.println(list); }} TestBench.java import java.util.AbstractList; public class TestBench { public static…
