public class kkk extends JComponent
{
    static File f1;
    int prog;
    static JFrame jf;
    int al;
    JLabel time;
    Timer tr;
    Button b;
    int pos=0;
    Clip c;
    AudioInputStream a;
    JSlider s;
    public static void main(String args[]) 
    {
        f1=new File("mm.wav");
        jf=new JFrame();
        jf.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
        kkk kp=new kkk(f1);
        jf.getContentPane().add(kp, "Center");
        jf.setSize(400,400);
        jf.setVisible(true);
    }
    kkk(File f1)
    {
        try
        {
            a=AudioSystem.getAudioInputStream(f1);
            AudioFormat af=a.getFormat();
            DataLine.Info di=new DataLine.Info(Clip.class,af);
            c=(Clip)AudioSystem.getLine(di);
            c.open(a);
        }
        catch(Exception e)
        {
            System.out.println("Exception caught ");
        }
        finally 
        {
            try
            {
                a.close();
            }
            catch(Exception e)
            {

            }
        }
        al=(int)(c.getMicrosecondLength()/1000); 
        s=new JSlider();
        Button b=new Button("play");
        time=new JLabel();
        Box row = Box.createHorizontalBox();
        row.add(s);
        row.add(b);
        row.add(time);
        b.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent eee)
        {
            play();
        }});
        s.addChangeListener(new ChangeListener(){
        public void stateChanged(ChangeEvent ee)
        {
            //repaint();
            prog=s.getValue();
            time.setText(prog / 1000 + "." + (prog % 1000) / 100);
            //if(prog!=ap)
            //skip(prog);
        }});
        tr = new javax.swing.Timer(100, new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                tick();
                }
                });
        setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
                this.add(row);
    }
    public void play()
    {
        try
        {
            FloatControl volume = (FloatControl) c.getControl(FloatControl.Type.MASTER_GAIN);
volume.setValue(-20.63f);
        }
        catch(Exception e)
        {}
        c.start();
        tr.start();
    }
    //public void skip(
    public void tick()
    {
          pos = (int) (c.getMicrosecondPosition() / 1000);
              s.setValue(pos);

You might get a little more help if you renamed your class 3 k's stand for an organization not well liked in America.
I'm no expert in java but I have a hitch that you want this to hook into another program to control the volume correct ?
I'm not sure how java names there system headers but I don't think that you have it listed. Also from reading your code as best I could you haven't told it what music player(do you mean an mp3 player or a program like windows media player) player you wanted it to change so it's just running the functions probably on thin air.

Edited by Celtrix: Added a little more than just rename class
