How do I reverse an int array in Java?

Question

I am trying to reverse an int array in Java.

This method does not reverse the array.

for(int i = 0; i < validData.length; i++)
{
    int temp =          


        

Answer 1

There are some great answers above, but this is how I did it:

public static int[] test(int[] arr) {

    int[] output = arr.clone();
    for (int i = arr.length - 1; i > -1; i--) {
        output[i] = arr[arr.length - i - 1];
    }
    return output;
}
