看看我的代码,为什么控制台中的第二行是170 10 121.

H是170,S是10,偏偏L是121.因为L必须小于100:

单击MenuItem NewGame时.它可以工作,但按F2不会

mntmNewGame.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent arg0) {
            int n = JOptionPane.showConfirmDialog(contentPane,"Do you want to play new game ?", "Message!", JOptionPane.OK_CANCEL_OPTION);
        }
    });

    mntmNewGame.addKeyListener(new KeyAdapter() {
        public void keyListener(KeyEvent e) {
            if(e.getKeyCode()==KeyEvent.VK_F2)
            {
                int n = JOptionPane.showConfirmDialog(contentPane,"Do you want to play new game ?", "Message!", JOptionPane.OK_CANCEL_OPTION);
            }
        }
    });
