What is polymorphism in Java OOP?

Polymorphism in Java OOP allows objects to be treated as instances of their parent class. It enables one interface to be used for a general class of actions.

Can you give me an example of polymorphism in Java?

Sure! For instance, if you have a class Animal with a method makeSound(), subclasses like Dog and Cat can implement this method differently. When you call makeSound() on an Animal reference, it will execute the method of the actual object type.

What are the two types of polymorphism in Java?

The two types of polymorphism in Java are compile-time (or static) polymorphism, which is achieved through method overloading, and runtime (or dynamic) polymorphism, which is achieved through method overriding.

How does polymorphism improve code flexibility?

Polymorphism improves code flexibility by allowing methods to use objects of different classes interchangeably, making it easier to extend and maintain code.
