hey,I want to ask about Java Sound API...using the code below, can I capture the audio coming from a microphone and send it using a Datagram packet?? if no, then please someone tell me what should I do...

private void captureAudio() {
try {
final AudioFormat format = getFormat();
DataLine.Info info = new DataLine.Info(
TargetDataLine.class, format);
final TargetDataLine line = (TargetDataLine)
AudioSystem.getLine(info);
line.open(format);
line.start();
Runnable runner = new Runnable() {
int bufferSize = (int)format.getSampleRate()
* format.getFrameSize();
byte buffer[] = new byte[bufferSize];

public void run() {
out = new ByteArrayOutputStream();
running = true;
try {
while (running) {
int count =
line.read(buffer, 0, buffer.length);
if (count > 0) {
out.write(buffer, 0, count);
buf=out.toByteArray();
sendPacket=new DatagramPacket ( buf,buf.length,address,portNumber);
socket.send(sendPacket);
}
}
out.close();
} catch (IOException e) {
System.err.println("I/O problems: " + e);
System.exit(-1);
}
}
};
Thread captureThread = new Thread(runner);
captureThread.start();
} catch (LineUnavailableException e) {
System.err.println("Line unavailable: " + e);
System.exit(-2);}
}

Please don't start a new thread with the same question. I've merged the two threads here.

Also, haven't you learned to format your code for readability? Code Conventions for the Java Programming Language: Contents
