2. If someone asks you if the class can be modified by private, I think the answer is yes, one of the benefits of the inner class.

1. internal classes can be very good to implement the hidden

The generic non-intrinsic class is not allowed to have private and protected permissions, but the inner class can

2. Inner class has access to all elements of the perimeter class

3. However, multiple inheritance is achieved

4. you can avoid modifying the interface and implementing the invocation of two methods of the same name in the same class.
