Adjustment problem

Question

How u add the getAdjustmentType( ) method with class variables : TRACK, UNIT_INCREMENT in the following code :
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;
public class WellAdjusted extends JFrame implements AdjustmentListener {
JTextField value = new JTextField("50", 30);
JScrollBar bar = new JScrollBar(SwingConstants.HORIZONTAL,
50, 10, 0, 100);
public WellAdjusted() {
super("Well Adjusted");
setSize(350, 100);
bar.addAdjustmentListener(this);
value.setHorizontalAlignment(SwingConstants.CENTER);
value.setEditable(false);
JPanel pane = new JPanel();
pane.setLayout(new BorderLayout());
pane.add(value, "Center");
pane.add(bar, "South");
setContentPane(pane);
public static void main(String[] arguments) {
JFrame frame = new WellAdjusted();
ExitWindow exit = new ExitWindow();
frame.addWindowListener(exit);
frame.show();
public void adjustmentValueChanged(AdjustmentEvent evt) {
Object source = evt.getSource();
if (source == bar) {
int newValue = bar.getValue();
value.setText("" + newValue);
repaint();

Answer 1

Is this what you want (see comment in code):
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;
public class WellAdjusted extends JFrame implements AdjustmentListener {
   JTextField value = new JTextField("50", 30);
   JScrollBar bar = new JScrollBar(SwingConstants.HORIZONTAL,   50, 10, 0, 100);
   public WellAdjusted() {
      super("Well Adjusted");
      setSize(350, 100);
      bar.addAdjustmentListener(this);
      value.setHorizontalAlignment(SwingConstants.CENTER);
      value.setEditable(false);
      JPanel pane = new JPanel();
      pane.setLayout(new BorderLayout());
      pane.add(value, "Center");
      pane.add(bar, "South");
      setContentPane(pane);
   public static void main(String[] arguments) {
      JFrame frame = new WellAdjusted();
      frame.addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent e) {
            System.exit(0);
      frame.show();
   public void adjustmentValueChanged(AdjustmentEvent evt) {
      Object source = evt.getSource();
      if (source == bar) {
         System.out.println(evt.getAdjustmentType()+" "+AdjustmentEvent.TRACK+" "+
            AdjustmentEvent.UNIT_INCREMENT+" "+AdjustmentEvent.UNIT_DECREMENT);    // is this what you want?
         int newValue = bar.getValue();
         value.setText("" +
            newValue);
      repaint();
}
