Creating and Disposing of a Form's Runtime Frame

To make your form work, you have to provide a runtime frame for it. The main() method for GUI forms takes care of creation and disposal of such frame.

To create a main() method for a form

  1. Open for editing the bound class of a form where you want to create the main() method.
  2. Press Alt+Insert.
  3. On the pop-up menu, click Form main(). The following method is added to the source code:
    public static void main(String[] args) { JFrame frame = new JFrame(" <class name> "); frame.setContentPane( new <class name>(). contentPane ); frame.setDefaultCloseOperation(JFrame. EXIT_ON_CLOSE ); frame.pack(); frame.setVisible( true ); }
