with Java please

K-Difference Complete the kDifference function in the editor below. It has two parameters: 1. An array of n positive distinct integers, a. 2. An integer, k. The function must return an integer denoting the total number of pairs of elements, (ai in array a where ai k a Input Format Locked stub code in the editor reads the following input from stdin and passes it to the function: The first line contains an integer, n, denoting the number of elements in array a. Each line i of the n subsequent lines (where 0 si k n) contains an integer describing a The last line contains an integer, k. Constraints 5 s n s 105 Each ai s 2 x 109 1 s k s 109 Output Format The function must return an integer denoting the number of pairs in array a whose difference is k. This is printed to stdout by locked stub code in the editor. Sample input 0 Sample output 0

Explanation / Answer

static int KDifference(int arr[], int k)

{

    int count = 0;

    for (int i = 0; i < a.length; i++)

    {

        for (int j = i+1; j < a.length; j++)

            if (arr[i] - arr[j] == k || arr[j] - arr[i] == k )

                  count++;

    }

    return count;
