Open the Java Application project created for WK1-exercise. (Included at the very bottom) This project should already have a main class file WK1.java. Add another main class file called WK2.java to the project as shown in class. Add the code below toWK2.java.

The following program converts a given string into an ArrayList. For example, the string java is converted into the ArrayList [J, a, v, a]. Your task is to create another string from this ArrayList where the word Java is jumbled. Remember, an ArrayList size changes as you add/remove items from it. I have provided algorithmic guideline for the code.

There are some errors in the code that you have to fix- only the bolded code needs to be changed or moved. No need to change anything else.Optional: Change this program so that it accepts user input (single word of any length) and jumbles it.

import java.util.*;

public class WK2 {

public static String createJumble(String word){

for (int i=0; i < word.length();i++){

//adding the "" to convert the char into a string

//this is a shortcut for converting char/numbers to string

wordList.add(word.charAt(i)+ ""); }

//this should print an ArrayList [J,a,v,a]

System.out.println(wordList);

//Now create a new string where you jumble the word Java

//A sample jumble: aJav

//the following generates a random number between 0-3

//you may need to use it in your code somewhere

//randomNum = (int)(Math.random()*4);

int randomNum = 0;

String jumble="";

//Your code goes here//Create a for loop that loops 4 times

//In the loop, create a random number

//Using the random number, get a letter from wordList

//Add the chosen letter to a string

//Remove this letter from the wordList

//(Think: What should be the range from which the random

//number is chosen? Remember you are removing items from

//the wordList as the loop progresses.)

return jumble;/**What happens when this line is removed? Why?**/ }

public static void main(String[] args) {

/**should wordList be declared here since this is local to this

method? Where should you place this line of code? **/

ArrayList wordList = new ArrayList();

String w = "Java";

/**how many arguments/inputs does createJumble take?

How many are here? If they mismatch, which one should you

remove from here?**/

String result = createJumble(w, w.length()); }}

WK1 exercise code:

package wk1and2;

import java.util.Arrays; import java.util.Scanner;

public class WK1and2 {

/** * @param args the command line arguments */ public static void main(String[] args) { Scanner in=new Scanner(System.in); System.out.println("Enter the phrase:"); String input=in.nextLine(); String[] phrase=input.split(" "); System.out.println(Arrays.toString(phrase)); //Declare a string variable for acronym String acronym=""; //Declare array for to store first letter of each word char[] charArray=new char[phrase.length]; //Iterate phrase array for(int i=0;i
