Java sound: how to play a file?

[john price]

How do I play a file? I converted an mp3 file to wav so I could use it with Java. I looked at some Java sound tutorials and they seemed way too hard. The ones that I found were good/easy were for applets... Could anyone give me a working example?
Thanks,

Not sure what you mean by "way too hard", but this doesn't look all that complicated.

public void music() {
	AudioPlayer MGP = AudioPlayer.player;
	AudioStream BGM;
	AudioData MD;
	ContinuousAudioDataStream loop = null;
	try {
	BGM = new AudioStream(new FileInputStream("UJKN.wav"));
	MD = BGM.getData();
	loop = new ContinuousAudioDataStream(MD);
	}
	catch (IOException ex) {}
	MGP.start(loop);
	}

How to get rid of the warnings?
I've already tried:

@SuppressWarnings("proprietary")

Which gave me no errors, but still the same 7 warnings.

From the link, what exactly should this line be:

stream = AudioSystem.getAudioInputStream(new URL("http://hostname/audiofile"));

My code is not supposed to be streaming from the internet. It is a local file...

I found another one online. I had to modify it because it was missing the Exception catching and the try clause. Anyway, here is what worked. Is this the way it is supposed to be?

public void music() {
	try {
	File soundFile = new File("UJKN.wav");
    AudioInputStream sound = AudioSystem.getAudioInputStream(soundFile);

    // load the sound into memory (a Clip)
    DataLine.Info info = new DataLine.Info(Clip.class, sound.getFormat());
    Clip clip = (Clip) AudioSystem.getLine(info);
    clip.open(sound);

    // due to bug in Java Sound, explicitly exit the VM when
    // the sound has stopped.
    clip.addLineListener(new LineListener() {
      public void update(LineEvent event) {
        if (event.getType() == LineEvent.Type.STOP) {
          event.getLine().close();
        }
      }
    });

    // play the sound clip
    clip.start();
	}
	catch (IOException e) {
	}
	catch (LineUnavailableException e) {
	}
	catch (UnsupportedAudioFileException e) {
	}
  }

You should never ignore these warnings. All classes in packages that start with sunw, sun or com.sun can change or be removed with any new release of Java. That's why they are undocumented. Using them may cause your programs to break when a new JRE / JDK is installed.

Okay, Thank you. Closing topic... Err...resolving it *clicks resolve*

It really goes without saying, but since you explicitly asked: you need to handle the exceptions in a meaningful way.

[Rob Spoor]

And that means to never ignore them but at least print their stack traces.

[Greg Charles]

OK, so the resolution is don't use sun.audio.AudioPlayer to play sounds; use javax.sound.sampled.AudioSystem, right? That's good to know!

Also, don't ignore warnings and don't swallow exceptions.
