Java Tutorial : Java Runtime Polymorphism(version2)

Animal.java

class Animal
{
    void whoAmI()
    {
        System.out.println("I am a generic Animal.");
    }
}

class Dog extends Animal
{
    void whoAmI()
    {
        System.out.println("I am a Dog.");
    }
}

class Lion extends Animal
{
    void whoAmI()
    {
        System.out.println("I am a Lion.");
    }
}

class Tiger extends Animal
{
    void whoAmI()
    {
        System.out.println("I am a Tiger.");
    }
}

RunTimePolymorphismDemo.java

public class RunTimePolymorphismDemo
{

    public static void main(String[] args)
    {
        Animal animalRef = new Animal();
        animalRef.whoAmI();

        animalRef = new Dog();
        animalRef.whoAmI();
        
        animalRef = new Lion();
        animalRef.whoAmI();
        
        animalRef = new Tiger();
        animalRef.whoAmI();     
    }

}

Output

I am a generic Animal.
I am a Dog.
I am a Lion.
I am a Tiger.
