How to create multiple instances for an inner class

Question

consider the following code

class A
 {
 Class B
  {
    ...
  }
 psvm()
  {
    B b= new A().new B(); //this one works
    B b[]=new A().new B[size]; //compile error
  }

how to go about?

@MadProgrammer,, I was thinking about hashtable implementation where the outer class is hashtable and inner class would be index nodes pointing to their respective chains,, is this correct?? btw , i didn't understand your comment... — Creative_Cimmons

You're creating an array of Bs. That is, you are creating a data structure that can store references to B objects. That data structure is not a B and therefore does not need an A to exist.

B b[] = new B[size];

You can use something like...

A.B[] c = new A.B[size];

But B may need to be declared public if you want to access it from outside the context of the package it is declared...

You can also import B

import your.awesome.packages.A.B;

Which will allow you to use...

B[] c = new B[10];
