What are advanced abstraction techniques in Java?

Advanced abstraction techniques in Java include interfaces, abstract classes, and design patterns like MVC.

Can you explain the difference between an interface and an abstract class?

Sure! An interface defines a contract with no implementation, while an abstract class can have both abstract and concrete methods.

When should I use an interface over an abstract class?

Use an interface when you want to define a contract for multiple classes without enforcing a common ancestor. Use an abstract class when you want to share code among closely related classes.

What are some design patterns that utilize abstraction?

Common design patterns that utilize abstraction include the Factory Pattern, Strategy Pattern, and Observer Pattern.
