Swing Examples - Slider with custom labels

Following example showcase how to use a slider with custom labels in a Java Swing application.
We are using the following APIs.
JSlider(orientation, min, max, value) − To create a slider while orientation set the vertical orientation.
JSlider(orientation, min, max, value) − To create a slider while orientation set the vertical orientation.
JSlider.getValue() − To get the current value of slider.
JSlider.getValue() − To get the current value of slider.
JSlider.setLabelTable() − To set the labels.
JSlider.setLabelTable() − To set the labels.
JSlider.setPaintLabels(true) − To show the labels.
JSlider.setPaintLabels(true) − To show the labels.
Create the following Java program using any editor of your choice in say D:/ > SWING > com > tutorialspoint > gui >
SwingControlDemo.java
package com.tutorialspoint.gui;
 
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import java.util.Hashtable;

public class SwingControlDemo {
   private JFrame mainFrame;
   private JLabel headerLabel;
   private JLabel statusLabel;
   private JPanel controlPanel;

   public SwingControlDemo(){
      prepareGUI();
   }
   public static void main(String[] args){
      SwingControlDemo  swingControlDemo = new SwingControlDemo();      
      swingControlDemo.showSliderDemo();
   }
   private void prepareGUI(){
      mainFrame = new JFrame("Java Swing Examples");
      mainFrame.setSize(400,400);
      mainFrame.setLayout(new GridLayout(3, 1));
      
      mainFrame.addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent windowEvent){
            System.exit(0);
         }        
      });    
      headerLabel = new JLabel("", JLabel.CENTER);        
      statusLabel = new JLabel("",JLabel.CENTER);    
      statusLabel.setSize(350,100);

      controlPanel = new JPanel();
      controlPanel.setLayout(new FlowLayout());

      mainFrame.add(headerLabel);
      mainFrame.add(controlPanel);
      mainFrame.add(statusLabel);
      mainFrame.setVisible(true);  
   }
   private void showSliderDemo(){
      headerLabel.setText("Control in action: JSlider"); 
      JSlider slider = new JSlider(JSlider.HORIZONTAL,0,100,10);
      Hashtable<Integer, JLabel> labelTable = 
      new Hashtable<Integer, JLabel>();
      labelTable.put(new Integer( 0 ),
      new JLabel("Stop") );
      labelTable.put(new Integer( 50 ),
      new JLabel("Slow") );
      labelTable.put(new Integer( 100 ),
      new JLabel("Fast") );
      slider.setLabelTable(labelTable);
      slider.setPaintLabels(true); 
      slider.addChangeListener(new ChangeListener() {
         public void stateChanged(ChangeEvent e) {
            statusLabel.setText("Value : " + ((JSlider)e.getSource()).getValue());
         }
      });
      controlPanel.add(slider);      
      mainFrame.setVisible(true);     
   } 
}
Compile the program using the command prompt. Go to D:/ > SWING and type the following command.
D:\SWING>javac com\tutorialspoint\gui\SwingControlDemo.java

If no error occurs, it means the compilation is successful. Run the program using the following command.
D:\SWING>java com.tutorialspoint.gui.SwingControlDemo
