How do I return to a class after I have called the run method in my new GUI?

So, I called run from another class. My main goal is to go back to the class I called it from using the submit button I created. Can anyone help me return to the class that called it via the submit button?

See How to Make Dialogues .
The modal dialog will block on code execution at the point where the dialog becomes visible and will return after the window is dismissed. Then you could get whatever you need from the object (so it can access it for you).
Alternatively, you can use the observer pattern and just call the class back when something has changed that it needs to know about.
