Question

所以我的代码可以正常运行；没有问题，或者至少我认为它没有任何问题；我需要添加两个最后的内容：第一个是发出蜂鸣声的方法（认为我必须使用工具包，actionListener等），第二个是打印程序生成的当前随机数的方法（类似toString）。我已经尝试过教授的方法来发出蜂鸣声，但是什么也没有，所以现在我在这里。预先感谢。

尝试了我教授代码中的一些方法，但一无所获。

        };

        ak.ask();

}

//Class Driver
package edu.pupr.LottoGame;

public class theLottoDriver {
    public static void main(String [] args) {

        theLotto lt = new theLotto(0);
        lt.start();

    }
}

输出应该是这样的：输入号码：3267

投掷＃1：4392

投掷＃2：8391

你输了！！！

如何在代码中实现“蜂鸣”声？
