What is static inner class?
An inner class declared as static is treated as if it were a normal top-level class.
What are inner classes?
Quite simply, an inner class is one class within another. Typically the inner class will be a private inner class, and will only be used by the outer class. class MyOuterClass { class MyInnerClass { } }
Can interface have inner class?
Yes
When do you use inner classes?
You use inner classes when you know you'll never need to access that class from anywhere else. A common use of this is in a linked list implementation: public class LinkedList { private class LinkedListNode { } } There's no reason for any other class to have access to your node class, so it should be an inner class.
What is a private class?
A private class is a class that cannot be directly accesed from outside its outer class, similar to a private variable or method. This means that a private class must always be an inner class, though an inner class can be public or protected instead. For instance, the following is valid and means that any X object cannot directly access the inner Y class. public class X { private class Y{} } The following however is invalid. private class X{}

Inner classes in java?

What happens when you declare class as a static in Java?
Declaring an inner class static means that class only has access to the "outer" class public and private static fields. A non-static inner class has access to the outer class's instance data. Top-level classes cannot be declared static. The advantage of a static inner class is that it doesn't need an instance of the containing class to work and it's bytecode class size is smaller for that reason - less overhead.
