What is polymorphism in Java and C++?

What is polymorphism in Java and C++?

Polymorphism is a core concept in object-oriented programming that allows methods to do different things based on the object it is acting upon. In Java and C++, it can be achieved through method overriding and interfaces.

Can you give me an example of polymorphism in Java?

Sure! In Java, you can have a base class called Animal with a method sound(). The subclasses Dog and Cat can override this method to provide their specific sounds. When you call sound() on an Animal reference, it will execute the overridden method of the actual object type.

How does polymorphism work in C++?

In C++, polymorphism is achieved using virtual functions. You declare a function as virtual in the base class, and then override it in derived classes. When you call the function through a base class pointer, it invokes the derived class's version.

What are the benefits of using polymorphism?

Polymorphism enhances code flexibility and reusability. It allows for easier maintenance and the ability to introduce new classes with minimal changes to existing code.
