    public static void main(String[] args) {
        try{
            File file = new File("audiodata/test.wav");
            AudioInputStream ain = AudioSystem.getAudioInputStream(file);

            AudioFormat format = ain.getFormat();
            DataLine.Info info = new DataLine.Info(Clip.class, format);

            Clip clip = (Clip) AudioSystem.getLine(info);
            clip.open(ain);

            clip.start();

        }catch(Exception e){
            e.printStackTrace();
        }
    }

I have written this simple main method to play the sound file, but it does not work. There is no Exception thrown. The program ends and I cannot hear anything. I have no idea, what my mistake is. Also creating the Clip by AudioSystem.getClip(); does not change anything.

    You are just starting the clip playing, one way or another you have to wait until it finishes playing. Currently you are just exiting before it has had a chance to get going. – greg-449 Jun 07 '17 at 13:46

The correct way to wait for a sound to finish playing is with a concurrency class like CountDownLatch, or with lower-level concurrency operations like wait/notify or Locks:

Clip clip = (Clip) AudioSystem.getLine(info);

CountDownLatch doneLatch = new CountDownLatch(1);

clip.addLineListener(new LineListener() {
    @Override
    public void update(LineEvent event) {
        if (event.getType().equals(LineEvent.Type.STOP)) {
            doneLatch.countDown();
        }
    }
});

clip.open(ain);
clip.start();

doneLatch.await();
