How do I implement polymorphism in Java?

How do I implement polymorphism in Java?

Polymorphism in Java allows methods to do different things based on the object that it is acting upon. You can implement it using method overriding and method overloading.

Can you give me an example of method overriding?

Sure! Here's a simple example: You have a base class Animal with a method sound(). The subclasses Dog and Cat can override this method to provide their specific sounds.

What about method overloading? How does that work?

Method overloading allows you to have multiple methods with the same name but different parameters. For example, you could have a method add(int a, int b) and another add(double a, double b).

Are there any best practices for using polymorphism?

Yes! Always prefer method overriding for runtime polymorphism, and use interfaces or abstract classes to define common behaviors.
