I have a GUI class with a menu of buttons and textfields. Depending on what choices that is made in the menu and the input, methods in the GUI class are calling methods in the Logic class to send the input and create new objects of Customer class and Account class and so on.

To be able to communicate between the GUI- and the Logic class, I first create an object of the Logic class and I do that inside the GUI class, since it’s here I have my main method. It this the best way to do it? Do I need some kind of reference variable between GUI- and Logic class or just use the reference when the object was created in the beginning of the GUI class? I guess to be able to communicate with a class, it must be an object first!? Thanks!

Logic logic = new Logic(); 

logic.addCustomer(name, number);

    I would instantiate the Logic class outside the GUI, but pass it as an argument to the GUI constructor. It’s nearly equivalent to what you are already doing, but I think it makes it clearer that the GUI uses a Logic object. Also, it’s possible that Logic does some other things before/after the GUI starts/closes; it might not be the case now, but it could be true in the future if you extend your program.

    Many other answers tell you to look at MVC, but that might be overkill for your project. It can decrease complexity for a large project, but increase it for a small one.

    EDIT:

    Logic login = new Logic();
...
MyGUI gui = new MyGUI(logic);
