What are some real-world examples of abstraction in Java?

Abstraction in Java is used to hide complex implementation details. For example, in a banking application, the user interacts with an interface for transactions without needing to know how the transactions are processed internally.

Can you give me another example?

Sure! In a vehicle management system, you might have an abstract class 'Vehicle' with methods like 'start()' and 'stop()'. Different vehicle types like 'Car' and 'Bike' would implement these methods differently.

How does abstraction help in software development?

Abstraction helps in reducing complexity by allowing developers to focus on high-level functionalities without worrying about the underlying details. It also promotes code reusability and easier maintenance.

Are there any design patterns that utilize abstraction?

Yes, design patterns like the Factory Pattern and the Strategy Pattern heavily utilize abstraction to define interfaces and allow for flexible implementations.
