How to process other task when reading the data from a file?

Question

Hello,
I met a problem. I created a GUI to control the audio data processing. When the "Start" button is pressed, a block of data is read from the audio file and processed, then loop.But other buttons or method cannot be operated in that procession until all data is processed.
How to let the other methods work under that circumstance? Should I use multiple threads?
The relative code:
SourceDataLine line;
boolean stop = false;
// When press "Start" button, the following method is invoked:
public void play(){
line.start();
int bytesRead = 0;
byte[] dataBuf = new byte[7500];
while (bytesRead != -1& !stop)
try
bytesRead = audioInputStream.read(dataBuf, 0, dataBuf.length);
catch (IOException e)
e.printStackTrace();
if (bytesRead >= 0)
int bytesWritten = line.write(dataBuf, 0, bytesRead);
line.drain();
// When press "stop" button, this method is invoked.
public void stop(){
stop = true;
line.stop();
// When press "***" button, the following button is invoked:
public void ***(){
Many thanks.Looking forward to getting your answer.

You have to use a seperate thread :
Wheb you press the start button, you have to make sure a seperate thread is started :
Thread runner = new Thread(){
public void run(){
//Here comes your code which reads the file
runner.start();
