Write a method swapArrayEnds() that swaps the first and last elements of its array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10}. The array's size may differ from 4:

import java.util.Scanner;

public class ModifyArray {

/* Display array values */ public void displayValues(int [] arrayVals) { int i;

for (i = 0; i < arrayVals.length; ++i) { System.out.print(arrayVals[i] + " "); } System.out.println(""); }

/* Your solution goes here */

public static void main (String [] args) { int numElem = 4; int[] sortedArray = new int[numElem]; ModifyArray numInverter = new ModifyArray();

// Add values to the array sortedArray[0] = 10; sortedArray[1] = 20; sortedArray[2] = 30; sortedArray[3] = 40;

numInverter.swapArrayEnds(sortedArray); numInverter.displayValues(sortedArray); } }

(bold the solution)
