Java please!

Consider the following method:

=====================================================

public static void funcArray(int[] a) {

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

a[i] = i + a[i - 1] - a[i];

}

}

=====================================================

Compute the contents of following arrays a1-3:

int[] a1 = {7, 3}; funcArray(a1);

int[] a2 = {4, 3, 6}; funcArray(a2);

int[] a3 = {2, 4, -1, 6, -2, 8}; funcArray(a3);
