How can I get notified when the user has moved a JSlider?

• There is no addActionListener method
• There is a method
  public void addChangeListener(ChangeListener l)
• Click on the ChangeListener link to learn more
• It has a single method:
  void stateChanged(ChangeEvent e)
• Apparently, method is called whenever user moves the slider
• What is a ChangeEvent?
  • It inherits getSource method from superclass EventObject
  • getSource: tells us which component generated this event
