What are some examples of polymorphism in software?

Polymorphism allows methods to do different things based on the object it is acting upon. For example, in object-oriented programming, a function can take objects of different classes as input.

Can you give me a specific example in Python?

Sure! In Python, you can have a base class called Animal with a method speak(). Then, subclasses like Dog and Cat can implement speak() differently. When you call speak() on an Animal reference, it will execute the appropriate method based on the actual object type.

What about polymorphism in Java?

In Java, polymorphism is often achieved through method overriding. For instance, if you have a superclass Shape with a method draw(), subclasses like Circle and Square can provide their own implementations of draw(). You can call draw() on a Shape reference, and it will invoke the correct method based on the actual object.

Are there any advantages to using polymorphism?

Yes, polymorphism enhances code flexibility and reusability. It allows for easier maintenance and the ability to introduce new classes without modifying existing code.
