import java.util.*;

class Animal {
	void show() {
		System.out.println("An Animal");
	}
}

class Dog extends Animal {
	void show() {
		System.out.println("A Dog");
	}
}

public class Lautturi {
	public static void main(String args[]) {

		Animal obj1 = new Animal();
		obj1.show();
		
		Dog obj2 = new Dog();
		obj2.show();
		
		Animal obj3 = new Dog();
		obj3.show();

	}
}
