New to sound

Question

I'm new to sound. I saw this program on the internet, but i'm not sure how to use it exactly. It says it needs a parameter (the name of the audio file) can anyone show me how to connect it to the main program?
public class SimpleAudioPlayer
     private static final int     EXTERNAL_BUFFER_SIZE = 128000;
     public static void main(String[] args)
          if (args.length != 1)
               printUsageAndExit();
          String     strFilename = args[0];
          File     soundFile = new File(strFilename);
          AudioInputStream     audioInputStream = null;
          try
               audioInputStream = AudioSystem.getAudioInputStream(soundFile);
          catch (Exception e)
               e.printStackTrace();
               System.exit(1);
          AudioFormat     audioFormat = audioInputStream.getFormat();
          SourceDataLine     line = null;
          DataLine.Info     info = new DataLine.Info(SourceDataLine.class,
                                                             audioFormat);
          try
               line = (SourceDataLine) AudioSystem.getLine(info);
               line.open(audioFormat);
          catch (LineUnavailableException e)
               e.printStackTrace();
               System.exit(1);
          catch (Exception e)
               e.printStackTrace();
               System.exit(1);
          line.start();
          int     nBytesRead = 0;
          byte[]     abData = new byte[EXTERNAL_BUFFER_SIZE];
          while (nBytesRead != -1)
               try
                    nBytesRead = audioInputStream.read(abData, 0, abData.length);
               catch (IOException e)
                    e.printStackTrace();
               if (nBytesRead >= 0)
                    int     nBytesWritten = line.write(abData, 0, nBytesRead);
          line.drain();
          line.close();
          System.exit(0);
     private static void printUsageAndExit()
          out("SimpleAudioPlayer: usage:");
          out("\tjava SimpleAudioPlayer <soundfile>");
          System.exit(1);
     private static void out(String strMessage)
          System.out.println(strMessage);
}

I'm not really sure what you mean by connecting it to the main program. That's a nearly complete program in itself. It's only missing two lines from the top:
import javax.sound.sampled.*;
import java.io.*;
Once you've added those (and compiled) it should run just fine from the command line: type "java SimpleAudioPlayer yoursoundfile.wav".
