java - Swing , Multiple Screens , Transfer of control

Question

I am developing a swing application. I am using two screens

1.A button from screen1 will launch screen 2.

PseudoCode :

ScreenA extends JFrame{

    onButtonClick(){
        Screen2.setVisible(true);
    }
    System.out.println("Hai");
}

Screen2 extends JFrame{
    onButtonClick{
         Hide this screen;
    }
}

Now the output is :

1. The screen 2 will be displayed 2.Hai will be printed.

My Objective : I want to display hai only when a button from screen 2 is clicked and screen 2 dissppears.

How do i achieve it ?

I tried setting a flag for buttonclicked in screen two. But the program just passes through the condition and goes on to the next line . How do i keep the control ?

Use a modal dialog. See How to Make Dialogs for more details.
