What are some real-world examples of interfaces and abstract classes?

Interfaces and abstract classes are fundamental in object-oriented programming. For example, in a payment system, you might have an interface called 'PaymentMethod' with methods like 'processPayment()'. Different classes like 'CreditCard' and 'PayPal' can implement this interface.

Can you give me more examples in different domains?

Sure! In a vehicle management system, you could have an abstract class 'Vehicle' with properties like 'speed' and methods like 'start()' and 'stop()'. Classes like 'Car' and 'Bike' would inherit from 'Vehicle' and implement specific behaviors.

What about in software development frameworks?

In frameworks like Java's Spring, you might find interfaces like 'ApplicationContext' that define methods for managing beans, while abstract classes like 'AbstractApplicationContext' provide a base for creating application contexts.

How do these concepts improve code quality?

They promote code reusability and flexibility. By using interfaces and abstract classes, you can define contracts and shared behavior, making it easier to manage and extend your code.
