import java.awt.event.*;
class ScrollbarEvent extends Frame implements AdjustmentListener
Scrollbar s;

    public ScrollbarEvent()
    private void createAndShowGUI()
        setTitle("Scrollbar with AdjustmentListener Demo");
        setLayout(new FlowLayout());
        // Create and add scrollbar
        s=new Scrollbar();
        // Make it fat!
        s.setPreferredSize(new Dimension(50,250));
        // Add adjustment listener
    // Called whenever the scrollbar value changes
    public void adjustmentValueChanged(AdjustmentEvent ae)
        // Update the title
        setTitle("Current value: "+ae.getValue());
    public static void main(String args[])
        new ScrollbarEvent();
