    sum += sq(d);
return sum;
intsumOfSquares(int numberOfTerms)
sum Of Squares 
return (int) (((double) numberOfTerms / 6) * (numberOfTerms + 1) * (2 * numberOfTerms + 1));
doublesumOfSquares(Number[] array)
Returns sum of all the squared elements in the array. 
double result;
int i;
result = 0.0;
for (i = 0; i < array.length; i++)
    result += array[i].doubleValue() * array[i].doubleValue();
return result;

if (in == null)
    return 0;
if (in instanceof int[]) {
    int[] inn = (int[]) in;
    int out = 0;
    for (int i = 0, s = inn.length; i < s; i++)
        out += inn[i] * inn[i];
    return out;
