I want to be able to play sound files in my program. Where should I look?

I wrote the following code that works fine. But I think it only works with .wav format.
public static synchronized void playSound(final String url) {
new Thread(new Runnable() {
// The wrapper thread is unnecessary, unless it blocks on the
// Clip finishing; see comments.
public void run() {
try {
Clip clip = AudioSystem.getClip();
AudioInputStream inputStream = AudioSystem.getAudioInputStream(
Main.class.getResourceAsStream("/path/to/sounds/" + url));
clip.open(inputStream);
clip.start();
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
}).start();
}

A bad example:
import sun.audio.*; //import the sun.audio package
import java.io.*;
//** add this into your application code as appropriate
// Open an input stream to the audio file.
InputStream in = new FileInputStream(Filename);
// Create an AudioStream object from the input stream.
AudioStream as = new AudioStream(in);
// Use the static class member "player" from class AudioPlayer to play
// clip.
AudioPlayer.player.start(as);
// Similarly, to stop the audio.
AudioPlayer.player.stop(as);

I didn't want to have so many lines of code just to play a simple damn sound. This can work if you have the JavaFX package (already included in my jdk 8).
private static void playSound(String sound){
// cl is the ClassLoader for the current class, ie. CurrentClass.class.getClassLoader();
URL file = cl.getResource(sound);
final Media media = new Media(file.toString());
final MediaPlayer mediaPlayer = new MediaPlayer(media);
mediaPlayer.play();
}
Notice : You need to initialize JavaFX. A quick way to do that, is to call the constructor of JFXPanel() once in your app :
static{
JFXPanel fxPanel = new JFXPanel();
}

For playing sound in java, you can refer to the following code.
import java.io.*;
import java.net.URL;
import javax.sound.sampled.*;
import javax.swing.*;
// To play sound using Clip, the process need to be alive.
// Hence, we use a Swing application.
public class SoundClipTest extends JFrame {
public SoundClipTest() {
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setTitle("Test Sound Clip");
this.setSize(300, 200);
this.setVisible(true);
try {
// Open an audio input stream.
URL url = this.getClass().getClassLoader().getResource("gameover.wav");
AudioInputStream audioIn = AudioSystem.getAudioInputStream(url);
// Get a sound clip resource.
Clip clip = AudioSystem.getClip();
// Open audio clip and load samples from the audio input stream.
clip.open(audioIn);
clip.start();
} catch (UnsupportedAudioFileException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (LineUnavailableException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
new SoundClipTest();
}
}

For whatever reason, the top answer by wchargin was giving me a null pointer error when I was calling this.getClass().getResourceAsStream().
What worked for me was the following:
void playSound(String soundFile) {
File f = new File("./" + soundFile);
AudioInputStream audioIn = AudioSystem.getAudioInputStream(f.toURI().toURL());
Clip clip = AudioSystem.getClip();
clip.open(audioIn);
clip.start();
}
And I would play the sound with:
playSound("sounds/effects/sheep1.wav");
sounds/effects/sheep1.wav was located in the base directory of my project in Eclipse (so not inside the src folder).

I created a game framework sometime ago to work on Android and Desktop, the desktop part that handle sound maybe can be used as inspiration to what you need.
Here is the code for reference.
package com.athanazio.jaga.desktop.sound;
import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;
import javax.sound.sampled.UnsupportedAudioFileException;
public class Sound {
AudioInputStream in;
AudioFormat decodedFormat;
AudioInputStream din;
AudioFormat baseFormat;
SourceDataLine line;
private boolean loop;
private BufferedInputStream stream;
// private ByteArrayInputStream stream;
/**
* recreate the stream
*
*/
public void reset() {
try {
stream.reset();
in = AudioSystem.getAudioInputStream(stream);
din = AudioSystem.getAudioInputStream(decodedFormat, in);
line = getLine(decodedFormat);
} catch (Exception e) {
e.printStackTrace();
}
}
public void close() {
try {
line.close();
din.close();
in.close();
} catch (IOException e) {
}
}
Sound(String filename, boolean loop) {
this(filename);
this.loop = loop;
}
Sound(String filename) {
this.loop = false;
try {
InputStream raw = Object.class.getResourceAsStream(filename);
stream = new BufferedInputStream(raw);
// ByteArrayOutputStream out = new ByteArrayOutputStream();
// byte[] buffer = new byte[1024];
// int read = raw.read(buffer);
// while( read > 0 ) {
// out.write(buffer, 0, read);
// read = raw.read(buffer);
// }
// stream = new ByteArrayInputStream(out.toByteArray());
in = AudioSystem.getAudioInputStream(stream);
din = null;
if (in != null) {
baseFormat = in.getFormat();
decodedFormat = new AudioFormat(
AudioFormat.Encoding.PCM_SIGNED, baseFormat
.getSampleRate(), 16, baseFormat.getChannels(),
baseFormat.getChannels() * 2, baseFormat
.getSampleRate(), false);
din = AudioSystem.getAudioInputStream(decodedFormat, in);
line = getLine(decodedFormat);
}
} catch (UnsupportedAudioFileException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (LineUnavailableException e) {
e.printStackTrace();
}
}
private SourceDataLine getLine(AudioFormat audioFormat)
throws LineUnavailableException {
SourceDataLine res = null;
DataLine.Info info = new DataLine.Info(SourceDataLine.class,
audioFormat);
res = (SourceDataLine) AudioSystem.getLine(info);
res.open(audioFormat);
return res;
}
public void play() {
try {
boolean firstTime = true;
while (firstTime || loop) {
firstTime = false;
byte[] data = new byte[4096];
if (line != null) {
line.start();
int nBytesRead = 0;
while (nBytesRead != -1) {
nBytesRead = din.read(data, 0, data.length);
if (nBytesRead != -1)
line.write(data, 0, nBytesRead);
}
line.drain();
line.stop();
line.close();
reset();
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
}

I'm surprised nobody suggested using Applet. Use Applet. You'll have to supply the beep audio file as a wav file, but it works. I tried this on Ubuntu:
package javaapplication2;
import java.applet.Applet;
import java.applet.AudioClip;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
public class JavaApplication2 {
public static void main(String[] args) throws MalformedURLException {
File file = new File("/path/to/your/sounds/beep3.wav");
URL url = null;
if (file.canRead()) {url = file.toURI().toURL();}
System.out.println(url);
AudioClip clip = Applet.newAudioClip(url);
clip.play();
System.out.println("should've played by now");
}
}
//beep3.wav was available from: http://www.pacdv.com/sounds/interface_sound_effects/beep-3.wav

This thread is rather old but I have determined an option that could prove useful.
Instead of using the Java AudioStream library you could use an external program like Windows Media Player or VLC and run it with a console command through Java.
String command = "\"C:/Program Files (x86)/Windows Media Player/wmplayer.exe\" \"C:/song.mp3\"";
try {
Process p = Runtime.getRuntime().exec(command);
catch (IOException e) {
e.printStackTrace();
}
This will also create a separate process that can be controlled it the program.
p.destroy();
Of course this will take longer to execute than using an internal library but there may be programs that can start up faster and possibly without a GUI given certain console commands.
If time is not of the essence then this is useful.

I faced many issues to play mp3 file format so converted it to .wav using some online converter
and then used below code (it was easier instead of mp3 supporting)
try
{
Clip clip = AudioSystem.getClip();
clip.open(AudioSystem.getAudioInputStream(GuiUtils.class.getResource("/sounds/success.wav")));
clip.start();
}
catch (Exception e)
{
LogUtils.logError(e);
}
