e800. Listening for Value Changes in a JSlider Component

    // Create horizontal slider
    JSlider slider = new JSlider();
    
    // Register a change listener
    slider.addChangeListener(new ChangeListener() {
        // This method is called whenever the slider's value is changed
        public void stateChanged(ChangeEvent evt) {
            JSlider slider = (JSlider)evt.getSource();
    
            if (!slider.getValueIsAdjusting()) {
                // Get new value
                int value = slider.getValue();
            }
        }
    });
