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

It is most efficient to simply iterate the array backwards.

I'm not sure if Aaron's solution does this vi this call Collections.reverse(list); Does anyone know?
