Consider the following class declarations.

class Alpha {
    int a = 2;
    int multiply() { return a * 3; }
}

class Beta extends Alpha {
    int a = 4;
    int multiply() { return super.multiply() + a; }
    public static void main(String[] args) {
        System.out.println(new Beta().multiply());
    }
}

What is printed when the program is executed?
