Inner Class instantiation through Interface Reference

[Jayavardhan geepi]

Hi..

I have compilation error with followinf

public interface A{}

public class B implements A{

//some methods

//nested class

public class NestedInB{

}

}

I need Object of NestedInB class.


I have code like this

A a = new B();
//Need code here to get Object of NestedInB
//Below code doesn't work
//Compiler says A.NestedInB can not be resolved to a type.

B.NestedInB = a.new NestedInB();

Can someone please help?

Your variable a is of type A (even though at runtime you're initializing it with a new B), and since class NestedInB is not in class A, this is not going to work.

You have to change a to a B:

B a = new B();
