What are some real-world uses of polymorphism in programming?

Polymorphism allows methods to do different things based on the object it is acting upon. For example, in a graphics application, a single function can be used to draw different shapes like circles, squares, or triangles, each implementing their own drawing method.

Can you give me another example?

Sure! In a payment processing system, you might have a base class called 'Payment' with subclasses like 'CreditCardPayment' and 'PayPalPayment'. Each subclass can implement a 'processPayment' method differently, allowing the system to handle various payment types seamlessly.

How does polymorphism improve code maintainability?

Polymorphism enhances maintainability by allowing you to write more generic code. When you can use a single interface to interact with different objects, it reduces the need for extensive conditional statements, making the code cleaner and easier to update.

Are there any downsides to using polymorphism?

Yes, while polymorphism offers flexibility, it can also introduce complexity. Overusing it can lead to code that is harder to understand and debug, especially if the relationships between classes become too intricate.
