Question

in java please fix code between 14 and 20 to make the code compile

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. Display ari ay Values 1 pas [ pa: 6 public void displayValues(int [] arrayVals) { 7 int i; 8 9 for (i = 0; i < arrayVals.length; ++i) { 19 System.out.print(arrayVals[i] + " "); 11 12 System.out.println(""); 13 } 14 public static void swapArrayEnds(int sortedArray[]) 15 { 16 17 int temp = sortedArray[0]; 18 sortedArray[0] = sortedArray[3]; 19 sortedArray[3] = temp; 20 } 21 public static void main (String[] args) { int numElem = 4; int[] sortedArray = new int[numElem); ModifyArray numInverter = new ModifyArray(); 22 23 24 25 26 // Add values to the array Run ✓ Testing with original sortArray = {10, 20, 30, 40} Your output 40 20 30 10 X Test aborted Exited with return code 1. Exception in thread "main" java.lang. ArrayIndexOutOfBoundsException: at main$ModifyArray.swapArrayEnds (main.java:436) at main.main(main.java:469)

`Hey,

Note: If you have any queries related to the answer please do comment. I would be very happy to resolve all your queries.

Your code will work only for the test case given but not for others. Below is the modified code

public static void swapArrayEnds(int sortedArray[])

{

int temp=sortedArray[0];

sortedArray[0]=sortedArray[sortedArray.length-1];

sortedArray[sortedArray.length-1]=temp;

}

Kindly revert for any queries

Thanks.
