What are some real-world applications of abstract classes in programming?

Abstract classes are used in programming to define a blueprint for other classes. For example, in a game development context, you might have an abstract class called 'Character' that defines common properties like health and methods like 'attack()'. Specific character types like 'Warrior' or 'Mage' would then inherit from this abstract class and implement their own versions of the methods.

Can you give me another example?

Sure! In a payment processing system, you could have an abstract class called 'PaymentMethod' with methods like 'processPayment()' and 'refund()'. Then, you could create subclasses like 'CreditCardPayment' and 'PayPalPayment' that implement these methods according to their specific requirements.

What are the benefits of using abstract classes?

The benefits include promoting code reusability, enforcing a consistent interface across different subclasses, and allowing for polymorphism, which makes it easier to manage and extend code.

Are there any drawbacks to using abstract classes?

Yes, one drawback is that they can introduce complexity into the codebase. If overused, they may lead to a situation where the hierarchy becomes too rigid, making it difficult to adapt to changes.
