Question

I have scenario like

Here is the abstract class

    abstract class A
    {
            public void add()
            {
                    //do something
            }
    }

Here is the class that extends above abstract class

    class B extends A
    {
            @Override
            public void add()
            {
                    //do something else
            }
    }

Here is the class in which I want to call both the add methods

    class C
    {
            A a = new B();

            // Calls B's add method

            a.add();

            // Call A's add method ???
    }

How to call A’s add method???

Answer 1

As explained above by various people, you can’t. If we try and understand as to what you want to achieve, i guess what you need is an interface and two classes.

interface AddInterface {
 public void add();
}

class A implements AddInterface {
//your abstract class' version of add goes here
}

class B implements AddInterface {
//your other add definition.
}

You end up replacing references to A with AddInterface.
Again, it all depends on what you want to achieve.
