How do I swap two integers in an array, where my method takes in two integers and an array from main?

Question

I call my swap method in main, but it doesn\'t change anything. What am I doing wrong?

public static void main(String[] args){


    int mainArr[] = new int[         


        

Answer 1

You are calling swapper the same number of times as there are elements in your array.

• If the array has a even length, nothing will change
• If the array has a odd length, it will change
