Java | Inheritance | Question 1

Output of following Java Program?

class Base {
    public void show() {
       System.out.println("Base::show() called");
    }
}

class Derived extends Base {
    public void show() {
       System.out.println("Derived::show() called");
    }
}

public class Main {
    public static void main(String[] args) {
        Base b = new Derived();;
        b.show();
    }
}

(A) Derived::show() called
(B) Base::show() called


Answer: (A)

Explanation: In the above program, b is a reference of Base type and refers to an object of Derived class.

In Java, functions are virtual by default. So the run time polymorphism happens and derived fun() is called.
