我有两个分别带有JFrame的Pane类。我还有另一个充当级别菜单的JFrame，当我打开一个JFrame时，两个计时器都启动了，我确定我缺少一些简单的东西，但是有人可以帮我吗。
第一级

第一个窗格（级别）的框架
窗格框架
private static final long serialVersionUID = 1L;
private Game_Model model= new Game_Model();
private Game_Pane p= new Game_Pane(model);
public Game_Frame() {
add(p);
setSize(600,600);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setTitle("Level 1");
}
第2层的窗格是相同的，框架也是一样，因为我还没有将其更改为唯一的，所以我也不会添加它。
级别菜单
private static final long serialVersionUID = 1L;
private JButton button= new JButton("1 player level 1");
private JButton button2= new JButton ("1 player level 2");
private JButton button3= new JButton ("2 player level 1");
private JButton button4= new JButton ("2 player level 2");
private Dimension d= new Dimension(300,50);
private Game_Frame Game_Frame= new Game_Frame();
private Game_Frame2 Frame2= new Game_Frame2();
public Level_Menu() {
setLayout (new GridBagLayout());
GridBagConstraints gbc= new GridBagConstraints();
gbc.gridwidth=GridBagConstraints.REMAINDER;
gbc.fill=GridBagConstraints.HORIZONTAL;
add(button,gbc);
add(button2,gbc);
add(button3,gbc);
add(button4,gbc);
button.setPreferredSize(d);
button2.setPreferredSize(d);
button3.setPreferredSize(d);
button4.setPreferredSize(d);
button.setBackground(Color.GREEN);
button2.setBackground(Color.green);
button3.setBackground(Color.GREEN);
button4.setBackground(Color.green);
setBackground(Color.BLACK);
button.addActionListener(this);
button2.addActionListener(this);
button3.addActionListener(this);
button4.addActionListener(this);
}
@Override
public void actionPerformed(ActionEvent e) {
Object a=e.getSource();
if (a==button) {
Game_Frame.setVisible(true);
}
else if (a==button2) {
Frame2.setVisible(true);
}
else if (a==button3) {
}
else if (a==button4) {
}
}
菜单框
private static final long serialVersionUID = 1L;
private Level_Menu level= new Level_Menu();
public Level_Frame() {
add(level);
setSize(600,600);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setTitle("Level Menu");}
