Count Comparisons In Java Quick Sort

I have to count the comparisons in the quick sort. I have done it by using a global variable. But I am stuck in doing it recursively.

This is my code.

import static java.time.Clock.system;
import java.util.Arrays;
public class test {
/**
* The swap method swaps the contents of two elements in an int array.
*
* @param The array containing the two elements.
* @param a The subscript of the first element.
* @param b The subscript of the second element.
*
*/
