Recursive Array Reversal

Consider the following processElements method. What is the result of calling this method on an integer array data with the initial call processElements(data, 0, data.length - 1)?

public void processElements(int[] data, int low, int high) 
{
    if (low < high) 
    {
        int temp = data[low];
        data[low] = data[high];
        data[high] = temp;
        processElements(data, low + 1, high - 1);
    }
}
