Create the following java program using any editor of your choice in say D:/ > SWING > com > tutorialspoint > gui >

package com.tutorialspoint.gui;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class SwingControlDemo {
   private JFrame mainFrame;
   private JLabel headerLabel;
   private JLabel statusLabel;
   private JPanel controlPanel;

   public SwingControlDemo(){

   public static void main(String[] args){
      SwingControlDemo  swingControlDemo = new SwingControlDemo();      

   private void prepareGUI(){
      mainFrame = new JFrame("Java Swing Examples");
      mainFrame.setLayout(new GridLayout(3, 1));
      mainFrame.addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent windowEvent){
      headerLabel = new JLabel("", JLabel.CENTER);        
      statusLabel = new JLabel("",JLabel.CENTER);    


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


   private void showSpinnerDemo(){
      headerLabel.setText("Control in action: JSpinner"); 
      SpinnerModel spinnerModel =
         new SpinnerNumberModel(10, //initial value
            0, //min
            100, //max
      JSpinner spinner = new JSpinner(spinnerModel);
      spinner.addChangeListener(new ChangeListener() {
         public void stateChanged(ChangeEvent e) {
            statusLabel.setText("Value : " 
            + ((JSpinner)e.getSource()).getValue());

Compile the program using command prompt. Go to D:/ > SWING and type the following command.

D:\SWING>javac com\tutorialspoint\gui\SwingControlDemo.java

If no error comes that means compilation is successful. Run the program using following command.

D:\SWING>java com.tutorialspoint.gui.SwingControlDemo
