Creating a Slider 

 
 int minimum = 0;
 int maximum = 100;
 int initValue = 50;
     
 // A horizontal slider.
 JSlider hSlider = new JSlider(
   JSlider.HORIZONTAL, minimum, maximum, initValue);
 hSlider.addChangeListener(new MyChangeListener());
     
 // A vertical slider.
 JSlider vSlider = new JSlider(
   JSlider.VERTICAL, minimum, maximum, initValue);
 vSlider.addChangeListener(new MyChangeListener());
     
 class MyChangeListener implements ChangeListener {
     public void stateChanged(ChangeEvent evt) {
         JSlider slider = (JSlider)evt.getSource();
         
         if (!slider.getValueIsAdjusting()) {
             int value = slider.getValue();
             process(value);
         }
     }
 }
