接下来是完成菜单栏的功能
游戏菜单
添加菜单监听器（com.panel/BombJMenuBar.java）
在init()方法中插入
// 开局事件处理
menuItemStart.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
mainframe.reStartGame();
}
});
// 添加事件监听器
MenuListener listener = new MenuListener(mainframe);
menuItemStart.addActionListener(listener);
menuItemLow.addActionListener(listener);
menuItemMid.addActionListener(listener);
menuItemHigh.addActionListener(listener);
menuItemOrder.addActionListener(listener);
menuHeroLow.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
new Hero(mainframe);
}});
menuHeroMid.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
new Hero1(mainframe);
}});
menuHeroHigh.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
new Hero2(mainframe);
}});
menuItemAbout.addActionListener(listener);
// 后门外挂方便测试
menuItemHole.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
}
});
menuItemExit.addActionListener(new ActionListener() { //加一个系统退出的处理监听
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});编写等级菜单监听类（com.listener/MenuListener）
// 等级菜单监听器
public class MenuListener implements ActionListener {
JMenuItem jMenuItem;
JTextField jTextField=new JTextField();
MainFrame mainframe;
public MenuListener(MainFrame mainframe){
this.mainframe = mainframe;
}
public void actionPerformed(ActionEvent e) {
if(e.getActionCommand().equals("开局(N)")){
this.mainframe.reStartGame();
}
if(e.getActionCommand().equals("初级(B)")){
Tools.rows = 9;
Tools.cols = 9;
Tools.allcount = 10;
Tools.currentLevel = Tools.LOWER_LEVEL;
this.mainframe.reStartGame();
}
if(e.getActionCommand().equals("中级(I)")){
Tools.rows = 16;
Tools.cols = 16;
Tools.allcount = 40;
Tools.currentLevel = Tools.MIDDLE_LEVEL;
this.mainframe.reStartGame();
}
if(e.getActionCommand().equals("高级(E)")){
Tools.rows = 16;
Tools.cols = 30;
Tools.allcount = 99;
Tools.currentLevel = Tools.HEIGHT_LEVEL;
this.mainframe.reStartGame();
}
if(e.getActionCommand().equals("自定义(C)")){
new UserDefined(mainframe);
}
if(e.getActionCommand().equals("关于扫雷(A)")){
new About(mainframe);
}
}
}注意：在雷区BombJPanel.java中之前是把行和列写成固定的，实现初级、中级、高级时要进行下述修改：
// MineLabel[][] labels = new MineLabel[9][9];
MineLabel[][] labels = new MineLabel[Tools.rows][Tools.cols];运行效果：
自定义菜单项（com.dialog/UserDefined.java）

英雄榜类（com.dialog/Hero.java）
英雄榜分为初级、中级、高级英雄榜；每个英雄榜类逻辑是一样的，通过胜利窗口的事件监听器判断是哪个等级的英雄榜数据，然后写入临时变量中保存。以此类推编写中级、高级英雄榜Hero1,Hero2，当然也可以只写一个类，不过需要多加一些判断条件。

// 后门外挂方便测试
menuItemHole.addActionListener(new ActionListener() {
