Java 所选变量不'；乒乓球比赛-秋千

我正试着用挥杆做一个乒乓球游戏。我有一个菜单屏幕，你可以改变你的喜好，如音乐，游戏速度，你可以选择多人游戏选项等。但当我做出选择时，它们的值不会改变。我有我的主菜单课和计算机课

例如：我想改变难度，这意味着改变人工智能的速度，但我没能做到。我期待着一个答案，也许很简单，但我看不到

这是我的代码：

public class MenuPanel

    private JPanel menuPanel;
    private JPanel optionsPanel;

    private JPanel gameEndPanel;
    JCheckBox twoPlayer;

    // creating the swing components and containers,
    // there are two frames to swap between them, 
    // we tried to use cardLayout but it didn't work for us. 

    public MenuPanel() {
        mainFrame = new JFrame("Welcome To Pong Game");
        mainFrame.setSize(700,700);

doneButton.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {

        optionsFrame.dispose();
        Pong pong = new Pong();

创建
Pong
类的新实例，并设置新创建实例的值

太长了，读不下去了。这个例子可能不在其他地方使用。您可能需要使用已经使用的<代码> Pong < /C> >，或者让其他类使用新创建的实例。
欢迎来到TL；DR；请发布。
doneButton.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {

        optionsFrame.dispose();
        Pong pong = new Pong();
