Question

section Four (20 marks) Assume methods to be defined from Question 1 to Question 3 in this section are public class ArrayMethods. defined in the 1. (4 marks) Write a private method called switchTwoArrays that accepts two integer arrays (assuming they are of same sizes) as parameters and switches the contents of the array by switching elements in the arrays. For example, it the program starts with first array: (14213]; second array: [112131: After invocation of switchTwoArrays, first array: (51412 ]: second array:[ 11213]: private void switchTwoArrays(int first, int Dj second) ilyour code starts here.

Answer 1

/*
 *  Java program to switch two arrays
 */

class Main
{
  private static void switchTwoArrays(int[] first, int[] second)
  {
    int temp;

    for (int i = 0; i < first.length; i++)
    {
      temp = first[i];
      first[i] = second[i];
      second[i] = temp;
    }

  }

  public static void printArray(int[] arr)
  {
    for (int i : arr)
    {
      System.out.print(i + " ");
    }
  }

  public static void main(String[] args)
  {
    int[] arr1 = {1,2,3};
    int[] arr2 = {4,5,6};

    System.out.print("Array 1: ");
    printArray(arr1);
    System.out.println();

    System.out.print("Array 2: ");
    printArray(arr2);
    System.out.println();

    switchTwoArrays(arr1, arr2);

    System.out.println("After Switching");
    
    System.out.print("Array 1: ");
    printArray(arr1);
    System.out.println();

    System.out.print("Array 2: ");
    printArray(arr2);
    System.out.println();
  }
}
/*  Program ends here */
