Java : How To Reverse Elements In An Array

public static void main(String[] args) {

        int[] myArray = {2,1,3,4,5}; // index : 0 1 2 3
        int len = myArray.length;

        int start = 0; // index 0
        int end = len -1; // index 3

        while(start < end) {

            int temp = myArray[start]; // 1
            myArray[start] = myArray[end]; // 4 => 1
            myArray[end] = temp; // 1 => 4

            start++;
            end--;
        }

        for(int i=0; i < len;i++) {
            System.out.println(myArray[i]);
        }

    }
