Java plays multiple clips at the same time
So my application needs to play the WAV file every time I click on the panel. But the problem now is that she waits for the first one to finish, until she plays the second. I want them to be able to play at the same time.
The reason I put Thread.sleep (500) is because if I don't, it won't play any sound at all :(

Update: Ok, so I made them play at the same time, but I want the stream to close when the clip finished playing, instead of waiting for the stream to be 500ms
How can i do this?

I always play several of these sounds. I am not spawning a new topic, as I believe javaSound is already triggering clips in another topic. The main "game loop" can continue to do its job. The app can register listeners for callbacks, or use receivers to see what the clips are doing.
Sometimes, if we want to make a multimedia or gaming application, it is easier to use getters. Running gameloop at 30-60fps gives us enough detail for most situations and we have complete control over what happens and when. This little testapp plays two wav files, the first one runs once, the second runs after 3 seconds, the second loop.

Try to check the source code of this open source program: DBoard .
You are especially interested in using the MediaPlayer class . You can call it using
(new Thread(new MediaPlayer(PATHTOFILE)).start();
