IntelliJ IDEA 12.1.0 Web Help

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+InsertCommand N; Command Enter.
  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);
}
