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 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

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 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

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

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

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

There is an alternative to importing the sound files which works in both applets and applications  convert the audio files into  java files and simply use them in your code   I have developed a tool which makes this process a lot easier   It simplifies the Java Sound API quite a bit   http   stephengware com projects soundtoclass
