Question

I created a GUI class and a demo class.
the demo class is calling to the GUI. I would like to run the GUI in a different thread.

GUI Class

public class UserGui extends JFrame {
public static void main(String[] args) {
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                UserGui frame = new UserGui();
                frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}
 }

Demo Class:

public class NNDemo {

    public static void main(String[] args) {
        UserGui gui = new UserGui();
        gui.setVisible(true);

    }
}

Answer 1

public class UserGui extends JFrame {
    public UserGui() {}

    public void showGui() {
        setVisible(true);
    }
}

public class Demo {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
             public void run() {
                  final UserGui GUI = new UserGui();
                  GUI.showGui();
             }

        });
    } 
}
