What are access modifiers in nested classes?

Access modifiers in nested classes determine the visibility of the nested class and its members. They include public, private, and protected.

Can you explain how a private nested class works?

A private nested class can only be accessed by its enclosing class. This encapsulation helps in hiding implementation details.

What about protected nested classes?

A protected nested class can be accessed by its enclosing class and by subclasses, allowing for more flexible inheritance.

Are there any examples of using these modifiers?

Sure! For instance, a private nested class can be used to implement helper methods that should not be exposed outside the enclosing class.
