Access modifiers for inner classes

Question

protected/public Inner Classes

I am sure the question has been asked already, but I wasn't able to find one so I'll ask...

I am curious what is the difference between private(protected) and public inner class. I am able to use both from out of the containing class using the outer class object.

public class A{
   private class B{

   }

   public static void main(String[] args){
     A a = new A();
     B b = a.new B();
   }
}

@Eng.Fouad: Yes, that is how one instantiates a non-static inner class in Java. — Ken Wayne VanderLinde, Aug 08 '11 at 20:12

A private inner class can still be accessed within the class that defined it.

If you have another class, B isn't visible:

public class C {
   public static void main(String[] args){
     A a = new A();
     B b = new B(); // compile error
   }
}

This is already the case, as B isn't static... – Fulluphigh May 16 '21 at 00:41

Actually, you are inside class A still, since the main method is a static method of class A
