Toolkit.getDefaultToolkit().beep();

Try this:

java.awt.Toolkit.getDefaultToolkit().beep();  

It worked for me, although I'm not sure whether this was the PC Speaker beep or some OS-generated beep.

它对我有用,虽然我不确定这是PC扬声器发出的蜂鸣声还是一些OS产生的蜂鸣声。

I read somewhere that you need to use a C/C++ dll and connect it with JNI, to make that work,.. link is offline

我在某处读到你需要使用C / C ++ dll并将其与JNI连接,以使其工作,...链接离线

好的,我找到了你要找的东西

Other than the beep sound you can try JFugue.

除了哔哔声,你可以试试JFugue。

    {
     If (whatever you named the file) = true
     Then
     Process.Start ("C:\Windows\Media\{whatever you named the file})
     }

I use that in C#. It's late for me the code is not exactly accurate before people bash this post. Put a write directory to name a folder and declare it the default location. Move the sound of your choice to this folder and it will play the audio tone. Set the timer in Java to loop the sound every 2 seconds to get the persons attention. Hope this helps as I'm learning my self!

我在C#中使用它。对于我来说,在人们抨击这篇文章之前,代码并不完全准确。放置一个写目录来命名文件夹并将其声明为默认位置。将您选择的声音移动到此文件夹,它将播放音频。在Java中设置计时器以每2秒循环一次声音以引起人们的注意。希望这有助于我学习自我!
