Thread: Playing sound in my nursing program

Well, I just joined this forum today. I am a nursing student who is trying to use Java as a way to make my nursing education more interesting, so I decided to create a program to help me and others study nursing. Well, I hit the wall very hard today. Java has been so amazingly fun to do, until I decided to add a bit of music into my code. Before I asked anyone, I searched google and found this code here:

package music4;
import java.io.File;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.SourceDataLine;

public class Music4
{
public static void main(String[]args)
{
String filename="lion2.wav"; (Here is where I name the file. Why is returning to me it cant find it. Please help)

int EXTERNAL_BUFFER_SIZE = 524288;

File soundFile = new File(filename);

if (!soundFile.exists())
{
System.err.println("Wave file not found: " + filename);
return;
}

AudioInputStream audioInputStream = null;
try
{
audioInputStream = AudioSystem.getAudioInputStream(soundFile);
}
catch(Exception e)
{
e.printStackTrace();
return;
}

AudioFormat format = audioInputStream.getFormat();

SourceDataLine auline = null;

//Describe a desired line
DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);

try
{
auline = (SourceDataLine) AudioSystem.getLine(info);

//Opens the line with the specified format,
//causing the line to acquire any required
//system resources and become operational.
auline.open(format);
}
catch(Exception e)
{
e.printStackTrace();
return;
}

//Allows a line to engage in data I/O
auline.start();

int nBytesRead = 0;
byte[] abData = new byte[EXTERNAL_BUFFER_SIZE];

try
{
while (nBytesRead != -1)
{
nBytesRead = audioInputStream.read(abData, 0, abData.length);
if (nBytesRead >= 0)
{
//Writes audio data to the mixer via this source data line
//NOTE : A mixer is an audio device with one or more lines
auline.write(abData, 0, nBytesRead);
}
}
}
catch(Exception e)
{
e.printStackTrace();
return;
}
finally
{
//Drains queued data from the line
//by continuing data I/O until the
//data line's internal buffer has been emptied
auline.drain();

//Closes the line, indicating that any system
//resources in use by the line can be released
auline.close();
}
}
}

I can't seem to make the program find the location of my file. No matter what I do it returns can't find the file. I copied into the same directory as the freakin program, and it still won't locate it. I hope I am over looking something very simplistic.

Please help me, I am very desperate in getting this part of my program to work.

You can check exactly where the file is being looked for with

if (!soundFile.exists())
{
    System.err.println("Wave file not found: " + soundFile.getAbsoluteFile());
    return;
}

Thank you so much

Damn, the problem is the music plays while my program stops. I Kind of want it to play in the backround of the program. Any quick tips.
