static Nested class:-
It has the fallowing feature:-
1.It is treated as a static data member as a class.
2.it can have both static and non static members.
3.It can access only static member of its inclosing(outer) class.
4.The object of this class can be created without creating its inclosing class object.
5.It can be inherite Independently.
6.It can also Inherite an other calss.
7.It can also implements an interface.
Note:-since it is treated as a static data member of a class so qualifies all those keyword that can be applied on a data member.
Syntex to crate the object:-
OuterclassName.nestedclassName referenceofNestedclass=new
outerclassName.nestedclassName(args if any)
NonStaticNested class:-
1.It is treted as a non-static data member of a class.

2.It can have only non-static member.

3.It can access all the members(static as well as non-static) of its inclosing class.

4.The object of this class always created with the help of its inclosing class object.

5.It can inherite other class.
Syntex to create the object of Non-static class:-
OuterClassName refofOuter=new OuterClassName(args if any);
OuterClassName.InnerClassName refofInner=ref of Outer.new InnerClassName(args if any);
Note:-In case of non-static nested class compiler make the fallowing changes int the source code.

class Outer
{
class Inner
{}
}
public static void main(String aa[])
{
Outer o=new Outer();
Outer.Inner in=o.new Inner();
}
}

During compilation:-

class Outer$Inner extends java.lang.Object
{
final Outer this$0;

Outer$Inner(Outer o)
{
this$0=0;
}

}
