        Container contentPane = frame.getContentPane();
        contentPane.setLayout(new FlowLayout());
        
        contentPane.add(new JLabel("Hello,World"));
        contentPane.add(new JButton("测试"));
        
        frame.setSize(400, 300);
        frame.setVisible(true);

    public static void main(String[] args)
    {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run()
