here are the codes.....

import java.awt.Dimension;
import java.awt.Font;
import java.awt.Point;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;

public class Application {
/**

* as argument.
*
* @param titleWindow title
* @param dimensionDimension of window
* @return instance of JFrame
*/
protected JFrame createMainFrame(String title, Dimension dimension) {

// create an instance of the window
JFrame frm = new JFrame(title);

// set the size of the window
frm.setSize(dimension);

// move the window to coordinate X:200, and Y:300
frm.setLocation(new Point(200,300));

return frm;
}
/**
* This section creates a menu bar instance that can be added in an
instance of
* JFrame.
*
* @return
*/
protected JMenuBar createMainMenu() {
// create the main menu bar
JMenuBar menuBar = new JMenuBar();

// create a menu holder
JMenu fileMenu = new JMenu("File");

// this change the font of the menu item
fileMenu.setFont(new Font("Tahoma", Font.PLAIN, 12));

// add the menu holder to the main menu
menuBar.add(fileMenu);

// to create a menu item that will hava an action use JMenuItem
JMenuItem newMenu = new JMenuItem("New...");
newMenu.setFont(new Font("Tahoma", Font.PLAIN, 12));
// add item to filemenu
fileMenu.add(newMenu);

/*
* Adding sub menus, to add sub menus you add an instance of JMenu
* within JMenu
*/
JMenu recentFiles = new JMenu("Recent Files");
// you dont need tochagne the font every time, i just want to use tahoma
recentFiles.setFont(new Font("Tahoma", Font.PLAIN, 12));
//add to file menu
fileMenu.add(recentFiles);

// then add JMenuItem in the newly create JMenu
JMenuItem item1 = new JMenuItem("File 1");
recentFiles.add(item1);
JMenuItem item2 = new JMenuItem("File 2");
recentFiles.add(item2);
JMenuItem item3 = new JMenuItem("File 3");

//adding a separator
fileMenu.addSeparator();

// adding exit menu item under file menu after the separator
JMenuItem exitMenu = new JMenuItem("Exit");
exitMenu.setFont(new Font("Tahoma", Font.PLAIN, 12));
// add item to filemenu
fileMenu.add(exitMenu);

/*
* associating an action to a menu; there are different ways to do
this but this is
* the simplest form; use the method addActionlistener()

is an inline
