Can we declare class as 'private' in java?

Question

I know that Java doesnt allow a top level class to be private however is there any way that the private classes are allowed apart from top level class?

Answer 1

You could use nested classes.

Answer 2

A class is a user-defined (custom) datatype and you can't declare a class in Java as private, but if you do not want to expose a particular user-defined data type (class) outside of another public class, then you can declare that as a nested/inner class (i.e., as a member of the public class). You can refer here for details.
