Program:

abstract class Favourite{
abstract void color();
}
//In real scenario, implementation is provided by others i.e. unknown by end user
class Ram extends Favourite{
	void color(){
		System.out.println("I am Ram, My Favourite color is Red");
		}
}

class Rahim extends Favourite{
	void color(){
		System.out.println("I am Rahim, My Favourite color is Green");
		}
}

//In real scenario, method is called by programmer or user
class Abstraction{
	public static void main(String args[]){
	Favourite s=new Rahim();//In real scenario, object is provided through method
	s.color();
	}
}

Output:

I am Rahim, My Favourite color is Green
