Task

Write a static method square(int n) in MathUtil that returns n * n.

Because it is static, main calls it on the class itself — MathUtil.square(6) — without ever building an object. The program prints 36.

Your solution

class MathUtil {
    // Write a static method square(int n) that returns n * n,
    // callable as MathUtil.square(...) with no object.

}

public class Main {

    public static void main(String[] args) {
        System.out.println(MathUtil.square(6));
    }
}
