JPopupMenu Example

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

import java.awt.*;
import java.awt.event.*;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JMenuItem;
import javax.swing.JPanel;
import javax.swing.JPopupMenu;

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

   public SwingJpopupMenu(){

   public static void main(String[] args){
      SwingJpopupMenu  swingMenuDemo = new SwingJpopupMenu();     
   private void prepareGUI(){
      mainFrame = new JFrame("Java SWING Examples");
      mainFrame.setLayout(new GridLayout(3, 1));

      headerLabel = new JLabel("",JLabel.CENTER );
      statusLabel = new JLabel("",JLabel.CENTER);        

      mainFrame.addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent windowEvent){
      controlPanel = new JPanel();
      controlPanel.setLayout(new FlowLayout());


   private void showPopupMenuDemo(){
      final JPopupMenu editMenu = new JPopupMenu("Edit"); 

      JMenuItem cutMenuItem = new JMenuItem("Cut");

      JMenuItem copyMenuItem = new JMenuItem("Copy");

      JMenuItem pasteMenuItem = new JMenuItem("Paste");

      MenuItemListener menuItemListener = new MenuItemListener();



      mainFrame.addMouseListener(new MouseAdapter() {
         public void mouseClicked(MouseEvent e) {            
            editMenu.show(mainFrame, e.getX(), e.getY());
   class MenuItemListener implements ActionListener {
      public void actionPerformed(ActionEvent e) {            
         statusLabel.setText(e.getActionCommand() + " MenuItem clicked.");

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

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

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

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