3.4 Methods — sum of squares

Total: 0 / 3 pts

Practice mode — check each part and get hints as you go.

Task

The helper square is already written above. Fill in sumOfSquares so that it returns the sum of the squares of a and b — by calling square, not by multiplying again yourself.

For sumOfSquares(3, 4) the program prints 25.

Your solution

public class Main {

    public static int square(int n) {
        return n * n;
    }

    public static int sumOfSquares(int a, int b) {
        // use the helper square twice

    }

    public static void main(String[] args) {
        System.out.println(sumOfSquares(3, 4));
    }
}
