I am hoping that someone on this list can set me straight !!

I have an app (below) that calls a class containing a Swing JFrame. My
understanding is that swing starts its own java thread (which explains the
issue i am seeing).

How do I Call a class (of swing JFrame) to gather information and have the
caller "wait" for a return???? (BTW JDialog will not provide enough
functionality for this app).

You can see my (feable) test attempt below. Where am I off course ???
TIA !

import javax.swing.JDialog;
public class test_caller {

        public static void main(String[] args) {
                test aWin = new test();
                aWin.show();
                System.out.println("From caller userid="+aWin.userid);
        }
}

        private void initialize() {
                this.setName("Main_JFrame");

                                        test.this.dispose();
                                        return;
                                }
                        });
