Coverting An Applet To An Application

Posted by Matt Gerrans on January 26, 2002 at 5:27 PM

Just add this main() method to your class:

    public static void main(String[] args) 
    {
        Applet applet = new Checkers();
        javax.swing.JFrame frame = new javax.swing.JFrame("Checkers");
        // To close the application:
        frame.setDefaultCloseOperation( javax.swing.JFrame.EXIT_ON_CLOSE );
        frame.getContentPane().add(applet);
        frame.setSize(400,300);
        applet.init();
        applet.start();
        frame.setVisible(true);
    }

Note that I used JFrame, which is a Swing component, whereas you were only using AWT. If you don't want to add Swing to the mix, you can easily change it to use Frame instead and add a window listener in place of the setDefaultCloseOperation() that looks like this:

    frame.addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent e) {
        System.exit(0);
      }
    });
