Java program:

1. Create an Arrays.java class in a folder called lab1 (do not use packages)
2. Using Java, implement the method Arrays.swapLargestAndSmallest(int[] a) that swaps the largest and smallest element in a. If there are multiple largest or smallest elements, pick the first one.
3. Run the following code to test your program.

public class Tester { public static void main(String[] args) { int[] a = new int[] { 5, 4, 1, 9, 2, 6 }; Arrays.swapLargestAndSmallest(a); System.out.println(java.util.Arrays.toString(a)); System.out.println("Expected: [5, 4, 9, 1, 2, 6]"); a = new int[] {1, 4, 1, 9, 2, 6}; Arrays.swapLargestAndSmallest(a); System.out.println(java.util.Arrays.toString(a)); System.out.println("Expected: [9, 4, 1, 1, 2, 6]"); a = new int[] {1, 4, 2, 9, 9, 6}; Arrays.swapLargestAndSmallest(a); System.out.println(java.util.Arrays.toString(a)); System.out.println("Expected: [9, 4, 2, 1, 9, 6]"); a = new int[] {1}; Arrays.swapLargestAndSmallest(a); System.out.println(java.util.Arrays.toString(a)); System.out.println("Expected: [1]"); } }
