 }



 public static boolean checkType(String chocie)
 {
     try {
        int num=Integer.valueOf(chocie);
        return true;
    } catch (Exception e) {
        return false;

总结：这里有五个类，一个是人类类（Human class),还有一个是电脑类（Computer Class),还有一个游戏类（Game Class),还有一个游戏测试类（TestMyGame Class)这个是主类,最后我加了一个工具类（Tool Class），为了不出现输入类型不对而导致出错的bug。
