'JFrame Not Appearing (mac issue?)

I am aware that several people have posted about this but no solution has worked for me. Can anyone tell me why a JFrame is not appearing from my code.

Code:

import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;

public class GUITestWindow extends JFrame{
    public void GUI(){
       setTitle("Welcome");
       setResizable(true);
       setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
       setSize(600,600);
       setVisible(true);

   }

    public static void main(String[] args){
        GUITestWindow a = new GUITestWindow();
        a.GUI();
    }
}

Thanks in advance!

I believe your problem is that you ran your commands in the wrong order. Sometimes, when setting up a JFrame, it will not appear if you run it in the run order. Try redoering:

setTitle("Welcome");
setResizable(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(600,600);
setVisible(true);

to:

setVisible(true);
setResizable(true);
setSize(600, 600);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setTitle("Welcome");

This doesn't always work, but it's worth a try. :)
