Provide a method that swaps the smallest and largest in an array of objects whose class implements the Comparable interface.

public class Comparables { /** Swaps the smallest and largest value. @param values an array of values of a class that implements the Comparable interface */ @SuppressWarnings("unchecked") // Needed for testing public static void swapMinAndMax(Comparable[] values) {

/* Your code goes here */

} }

import java.util.Arrays; public class Tester { public static void main(String[] args) { String[] values1 = { "Fred", "Wilma", "Barney" }; Comparables.swapMinAndMax(valuesl); System.out.println(Arrays.toString(valuesl)); System.out.println("Expected: [Fred, Barney, Wilma]"); Integer[] values 2 = { 1, 4, 9, 16, 25 }; Comparables.swapMinAndMax(values2); System.out.println(Arrays.toString(values2)); System.out.println("Expected: [25, 4, 9, 16, 1]"); Integer[] values 3 = { 1 }; Comparables.swapMinAndMax(values3); System.out.println(Arrays.toString(values3)); System.out.println("Expected: [1]"); } }
