        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();

          pos = (int) (c.getMicrosecondPosition() / 1000);
              s.setValue(pos);
    }
}

But i am not able to increase and decrese the volume....i am not able to control the volume....the program compiled successfuly but ....didn't able to control the volume label....please help me guys.

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 5 Years Ago by Celtrix: Added a little more than just rename class
