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

static int[] reverseArray(int[] a) {
     int ret[] = new int[a.length];
     for(int i=0, j=a.length-1; i=0; i++, j--)
         ret[i] = a[j];
     return ret;
}
