An inner class declared as static is treated as if it were a normal top-level class.
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 { } }
Yes
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.
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{}

An inner class is a class within a class: class MyClass { class MyInnerClass { } } Inner classes in Java are normally used for things like the nodes of a linked list.
A class declared as a member of another class is called as a nested class or a class with in class. the general syntax of the nested class is: class outer_class_name{ private: //data protected: //data public: //methods class inner_class_name{ private: //data of inner class public: //methods of inner class };//end of inner class };//end of outer class

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.
It is a declaration of java class in method body which called "inner class"
