Static Inner class -Doubt ,in K & B

[Lucky J Verma]

I have a doubt in Static Inner Class- Question form K & B Book pg 665.code is :->
class MyOuter{
public static class Inner{
public static void foox(){}
}
}
public class Test11{
public static void main(String args[])
{
//MyOuter.Inner m= new MyOuter.Inner();//correct
MyOuter m=new MyOuter();
MyOuter.Inner mi=m.new MyOuter.Inner();//WRONG
}
}

-------------------------------
In this Question ,we have to tell correct instantion of inner class.

one is ,with outer class'es Name only,no oter instance, needed.

2nd one ,i tried ,its compiler error .but i could nit justfy the reason.
As with static member,s Right way to access is CLASSNAME.VARNAME ...but still not illegal way is OBJNAME.VARNAME
why its not feasibile in staticinner class class.
it outerobj.new inner();

Here class Inner is not an inner class but a nested class.
Inner class: Inner class has access to the members of the outer class and cannot exists without outer class instance.
Static inner classes or it should be more appropriately called static nested class does not meet the condition of the inner class.
Hence to instantiate a static nested class all you need to just instantiate it just like anyother class.
MyOuter.Inner m= new MyOuter.Inner();//correct
Here the refernce is declared as MyOuter.Inner this gives the complete path name of the static nested class Inner and same applies the in the instantiation syntax.
Now when you try
MyOuter.Inner mi=m.new MyOuter.Inner();//WRONG
Is in correct because you are trying to instantiate a static nested class with its outer class instance.

Hope its clear, Just read the difinition of the inner class and static nested class it will be clear.
Thanks
