What are the benefits of using inner classes in Java?

Inner classes in Java provide better encapsulation, improved readability, and can access the outer class's members directly.

Can you explain how inner classes improve encapsulation?

Sure! Inner classes can hide their implementation details from the outside world, allowing for a cleaner API.

Are there any performance benefits to using inner classes?

Yes, inner classes can lead to better performance in certain scenarios by reducing the overhead of creating separate class files.

What about the readability aspect?

Inner classes can make the code more readable by logically grouping classes that are only used in one place.

Can you give an example of when to use an inner class?

Certainly! If you have a class that represents a complex data structure, an inner class can represent its nodes, keeping related code together.
