What are some use cases for inner classes in Java?

Inner classes in Java are used for logically grouping classes that are only used in one place, enhancing encapsulation.

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

Sure! An inner class can be used to create a data structure, like a linked list, where each node is an inner class of the list.

What are the benefits of using inner classes over regular classes?

Benefits include better organization of code, increased encapsulation, and the ability to access the outer class's members directly.

Are there any performance implications of using inner classes?

Generally, inner classes have a slight overhead due to their association with the outer class, but the impact is usually minimal.

Can inner classes be static?

Yes, inner classes can be static. A static inner class does not have access to instance variables of the outer class.
