How do I reverse an int array in Java?

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 = validData[i];    validData[i] = validData[validData.length - i - 1];    validData[validData.length - i - 1] = temp;}

What is wrong with it?
