Will the following code compile?

abstract class A {

public int do_stuff1() {

return 3;

}

}

class B extends A {

@Override

public int do_stuff1() {

return 4;

}

public int do_stuff2() {

return 7;

}

}

class Main {

public static void main(String[] args) {

//Note the polymorphism:

A myB = new B();

myB.do_stuff1();

myB.do_stuff2();

}

}

No, Class C can't extend one class (B) and implement an interface (1A), it can only do one or the other. No, Class C doesn't correctly override do_stuff2() No, class C cannot be instantiated because it implements an interface. Yes
