instantiate objects in inner class in their methods. see how and why?

[Aruna Agrawal]

public class TestClass
{
public class A
{
}
public static class B
{
}
public static void main(String args[])
{
class C
{
}
//1
}
}
 
Select 2 correct options 
a  new TestClass().new A();  
b  new TestClass().new B(); 
c  new TestClass.A();   
d  new C()
e  new TestClass.C()
  

Ans: a and d
Why b is wrong???

B is a static class and therefore does not need an instance of A to be created.

it does not need is fine.. but what harm is there if i give it..why compiler complains.. compiler is surely cheating in this case..
similar analogy : to access static method we dont need a object. but if u call on object its fine..

Hey
There is no such thing as a static class ..The static modifier just says that its a static member of the outer class. AND it can be acessed without an instance of the outer class!!!

class A{
static class B{}
}
class test
static public void main(Sring ar[])
{
A.B x=new A.B();
}
There is no instance of the outer class here the new apllies to the inner class which is being acessed thru the outer

From Aruna,

why compiler complains.. compiler is surely cheating in this case..

I dont think compiler complains about having a statement as
"new TestClass().new B(); "

I guess the question is quite vague. It should ask as
select 2 appropriate options

Hi,

 public class TestClass {
public class A {
}
 
public static class B {
}
 
public static void main(String args[]) {
class C {
} 

new TestClass().new B(); //Compiler DOES hate this
}
} 

Cheers,

Si.
