    Default Trying to create a window...

    Here's my code:

    import javax.swing.* ;

    class Window extends JFrame

    {
    public static void main ( String[] args){
    }
    JPanel pnl = new JPanel() ;
    public Window()
    {
    super( "Swing Window" ) ;
    setSize( 500, 200 ) ;
    setDefaultCloseOperation( EXIT_ON_CLOSE ) ;
    add( pnl ) ;
    setVisible( true ) ;
    }
    Window gui = new Window() ;
    }

    When I run it with Bluej I get a flickering window that doesn't seem right. Any thoughts? Thanks in advance.

    Java will start running what is in your main method. Well what is currently in your main method?

    public static void main ( String[] args){
      // not much here!
    }

    I think you'll want to put some relevant code in there so that Java will have some code to run. Experiment with this, try different things, and you'll see. Also please read the tutorials as this is all explained there quite well.

    Please read the announcements thread for instructions on how to wrap your code to preserve formatting.
