import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; import javax.swing.BoundedRangeModel; import javax.swing.JFrame; import javax.swing.JSlider; import javax.swing.event.ChangeEvent; import javax.swing.event.ChangeListener; public class Main extends JFrame {

Using BoundedRangeModel

The interface contains four interrelated properties that are necessary to describe a range of values: minimum, maximum, value, and extent.

The settings for the four properties must abide by the following ordering:

   <source lang="java">

minimum <= value <= value+extent <= maximum</source>
