Record while holding down a JButton - is that possible?

Question

I'm gonna make a program that records while the user is pressing and holding down the Record button. Is that possible? How can I do it?
I have started with this code where I am using a mouseListener for the button and not an actionListener, that´s because I think a mouseListener is better if I want to implement a function that makes it possible to hold down the button while recording. Am I right? How can I write such a method?
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
import java.net.*;
import javax.sound.sampled.*;
class Recorder extends JFrame
     private JButton recordButt = new JButton("Record");
     private Socket sock = new Socket();
     private AudioFormat audioFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 44100.0F, 16, 2, 4, 44100.0F, false);
     private AudioFileFormat fileFormat = new AudioFileFormat(AudioFileFormat.Type.WAVE, audioFormat, 16);
     private AudioInputStream ais;
     private TargetDataLine tdl;
     private File file = new File("sound.wav");
     Recorder()
          super("Recorder");
          setLayout(new BorderLayout());
          JPanel north = new JPanel();
          add(north, BorderLayout.NORTH);
          north.add(recordButt);
          recordButt.addMouseListener(new RecordButt());
          setDefaultCloseOperation(EXIT_ON_CLOSE);
          pack();
          setVisible(true);
     class RecordButt extends MouseAdapter
          Record r = new Record();
          public void mousePressed(MouseEvent e)
               r.start();
          public void mouseReleased(MouseEvent ee)
               r.interrupt();
     class Record extends Thread
          public void start()
               DataLine.Info info = new DataLine.Info(TargetDataLine.class, audioFormat);
               try
                    tdl = (TargetDataLine)AudioSystem.getLine(info);
                    tdl.open(audioFormat);
               catch(LineUnavailableException err) { System.out.println(err.getMessage()); }
               ais = new AudioInputStream(tdl);
               try
                     AudioSystem.write(ais, AudioFileFormat.Type.AU, file);
               catch(IOException e) {}
               tdl.stop();
               tdl.close();
     public static void main(String[] args)
          new Recorder();
}

Thanks!
I have modified the above code and I have marked the changes with the comment "marked" and now it looks like:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
import java.net.*;
import javax.sound.sampled.*;
class Recorder extends JFrame
     private JButton recordButt = new JButton("Record");
     private Socket sock = new Socket();
     private AudioFormat audioFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 44100.0F, 16, 2, 4, 44100.0F, false);
     private AudioFileFormat fileFormat = new AudioFileFormat(AudioFileFormat.Type.WAVE, audioFormat, 16);
     private AudioInputStream ais;
     private TargetDataLine tdl;
     private File file = new File("sound.wav");
        boolean record = false;  // changed
     Recorder()
          super("Recorder");
          setLayout(new BorderLayout());
          JPanel north = new JPanel();
          add(north, BorderLayout.NORTH);
          north.add(recordButt);
          recordButt.addMouseListener(new RecordButt());
          setDefaultCloseOperation(EXIT_ON_CLOSE);
          pack();
          setVisible(true);
     class RecordButt extends MouseAdapter
          Record r = new Record();
          public void mousePressed(MouseEvent e)
                      record = true;   // changed
               r.start();
          public void mouseReleased(MouseEvent ee)
               record = false;   // changed
     class Record extends Thread
          public void start()
               DataLine.Info info = new DataLine.Info(TargetDataLine.class, audioFormat);
               try
                    tdl = (TargetDataLine)AudioSystem.getLine(info);
                    tdl.open(audioFormat);
               catch(LineUnavailableException err) { System.out.println(err.getMessage()); }
               ais = new AudioInputStream(tdl);
               try
                              while(record)   // changed
                           AudioSystem.write(ais, AudioFileFormat.Type.AU, file);
               catch(IOException e) {}
               tdl.stop();
               tdl.close();
     public static void main(String[] args)
          new Recorder();
}But the Record button seems to hang while beeing pressed. Why?
