Problem 2 - Java

Implement the swapNext method in the Problem02 class. Its purpose is to swap the elements at indices i and i + 1. For example, when i is 3, it should swap the elements at indices 3 and 4.

The expected output of this program when swapNext is correctly implemented is:

Implement the swapNext method in the Problem02 class. Its purpose is to swap the elements at indices i and i + 1. For example, when i is 3, it should swap the elements at indices 3 and 4. The expected output of this program when swapNext is correctly implemented is: 0: e 1:a 2:b 3:d 4:c There is nothing for you to do in Problem 3. Continue to Problem 4.

Explanation / Answer

Problem02.java

public class Problem02 {
   public static void swapNext(char a[], int i){
       char temp;
       temp = a[i+1];
       a[i+1] = a[i];
       a[i]=temp;
   }

   public static void main(String[] args) {
       int[] indices = new int[]{3,2,3,1,0};
       char a[] = new char[]{'a','b','c','d','e'};
       for(int i: indices){
           Problem02.swapNext(a, i);
       }
       for(int i=0; i<a.length; i++){
           System.out.println(i + ":"+a[i]);
       }
   }

}

Output:

0:e
1:a
2:b
3:d
4:c
