How do I access methods inside of a nested class?

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.

As far as I know, you can't. Nor can you access that method if you created an instance of SuperClass. The only way that you can access that method is if you create an instance of InnerClass.

I can create an instance of InnerClass from inside Super or Sub class, but not the Tester class. I need to if there is any way to either create an instance of InnerClass from within Tester, or to simply access its methods.

Code:

---


public class Tester  {
    SuperClass.InnerClass object = new SuperClass().new InnerClass();
    SubClass.InnerClass object2 =  new SubClass().new InnerClass();
    public  void myTest1() {
        // How do I make the following line work?
        System.out.println(object.isTrue());
       
        System.out.println(object2.isTrue());
    }
   
    public static void main(String[] args) {
        new Tester().myTest1();
    }
}

public class SuperClass {
    // nested class
    public class InnerClass{
        public boolean isTrue(){
              boolean isTrue = false;           
              return isTrue;

        }
    }
}

public class SubClass extends SuperClass{
    // stuff
}

Your nested class is non-static, so it is only meaningful in the instance of your outer class. Hope this helps.
