                    int index2)

        Parameters:
        array - Array being sorted.
        index1 - The index in the given array of the first element to compare.
        index2 - The index in the given array of the second element to compare.
        Returns:
        The implementation must return a number less than, equal to, or greater than zero to indicate whether the array element at index1 should be considered less than, equal to, or greater than the array element at index2.
