    public static void main(String[] args) {
   
        try {
   
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); //设置UI

        JFrame frame = new JFrame("记事本 - "+ file);
        frame.setVisible(true);


        frame.setBounds(100,100,700,500);

                System.exit(0);
            }
        });
