Say I have this code...

Code:
public class SuperClass {

     // nested class
     public class InnerClass{

          public boolean isTrue(){

               return boolean;

          }

     }

}
Code:
public class SubClass extends SuperClass{

     // stuff

}
Code:
public class Tester  {

     SubClass object = new SubClass();

     // How do I make the following line work?
     System.out.println(object.isTrue());

}
Thanks.
