Question

I know this is probably pretty basic, and I’m ashamed for not knowing how to do this (and worse yet, being unsuccessful in searching for a solution).

How would I pass an object of type thing from A to C?

public class A extends B {

}

public class B {

    public class thing {

    }

}

public class C extends JFrame {

}

I have access to thing in A because I’m extending B, but I’m unable to extend B when using class C because I need to extend JFrame.

EDIT

Sorry for the vagueness. Class A has a collection of objects of type thing and I want to iterate through those objects in class C.

EDIT 2

And of course… the obvious choice. Make thing its own class… 🙁

Admitting shame for the sake of those who may also have an issue like this.

Answer 1

First, if it’s an inner class – you probably shouldn’t access it from the outside…

But, if you insist, you can try to do as follows:

public class A extends B {

}

public class B {

    public class thing {

    }

    private thing mything = new thing();
    public thing getThing(){
      return mything;
    }

}

public class C extends JFrame {
      A a = new A();
      Object thing = a.getThing();
}
