Setting up main-class to incorporate multiple JFrames/Gui Forms

Question

I'm using IntelliJ IDEA, and I have created two GUI forms I want to use as screens for my application. However I am stuck on how to get my separate main-class to incorporate the two JFrames, and how to control the switch from one JFrame to another. In the code below in the main-class, I'm first initializing an object of both GUI forms, afterwards I'm running the setup-frames 'run' method, which sets the frame visible. This step works.

Now I want an actionListener on my button 'udførButton' which gets the values typed in it's TextFields, so that I can use them as parameters to initialize an instance of the 'Billetautomat' class. Furthermore, I want the button to close the 'setup' JFrame and to start up the 'gui' JFrame with the gui.run() method.

My intended flow in the program is:

1. Run 'setup' gui, where I can type in three names and three ints
2. Run 'gui' (not done designing yet), where I can press multiple buttons to trigger different actions
3. Run other JFrames for non-specified actions and return to 'gui' (step 2)

Problem is, that the actionListener won't work as I want it to... If I change the code inside the actionListener to billet1Label.setText("HELLO"); it indeed changes the Label's text to display HELLO, but I can't make it work as I intend... I think the problem is that the program doesn't stop and wait for my button click, but just races through the main code... Do I need some sort of check to see if the button has been pressed, or have you got any expert-advise? This is my first time working with Swing in Java, so please be patient with me...

The final and the [] on the variables was suggested by IntelliJ....
