How to loop the audio file: play again after it ends javax.sound.sampled

I'm trying to play a sound over and over. I have this code:

public void play()  {
        try  {
            URL defaultSound = getClass().getResource(filename);
            AudioInputStream audioInputStream =
                    AudioSystem.getAudioInputStream(defaultSound);
            Clip clip = AudioSystem.getClip();
            clip.open(audioInputStream);
            clip.start( );
            System.out.println(clip.getMicrosecondLength());
            Thread.sleep(clip.getMicrosecondLength() / 1000);
            clip.addLineListener(new LineListener() {
                @Override
                public void update(LineEvent event) {
                    try {
                        clip.start();
                        Thread.sleep(clip.getMicrosecondLength() / 1000);
                    }
                    catch (Exception e)  {
                        e.printStackTrace();
                    }
                }
            });

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

but it only plays the sound once.

clip.open(audioInputStream);
clip.start( );

Should be:

clip.open(audioInputStream);
clip.loop(Clip.LOOP_CONTINUOUSLY); // <- NEW!
clip.start( );

See Clip.loop(int):

Parameters:
count - the number of times playback should loop back from the loop's end position to the loop's start position, or LOOP_CONTINUOUSLY to indicate that looping should continue until interrupted

You're going to want to likely set the Clip's frame position using Clip#setFramePosition to 0. You will want to call this before Clip#start. You also need to check if the LineEvent type is the value LineEvent.Type#STOP to ensure the event is an update event or close, and it is indeed when it stops.

@Override
public void update(LineEvent event) {
    try {
        if (event.getType() == LineEvent.Type.STOP) {
            clip.setFramePosition(0);
            clip.start();
            Thread.sleep(clip.getMicrosecondLength() / 1000);
        }
    } catch (InterruptedException e)  {
        Thread.currentThread().interrupt();
    }
}
