Creating Menu Like Buttons in Swing

Buttons acting like menus in Java. It's just like what you have seen in Windows 7 and in most software. It is like Menus without a MenuBar. It is dead simple.

import javax.swing.*;
import java.awt.*;
class MenuButton extends JFrame
{
JMenuBar menuBar;
JMenu menu;
JMenuItem newFile,open,save,saveas,exit;

    public MenuButton()   
    {
    setTitle("Menu Button");
    setVisible(true);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    setLayout(new FlowLayout());
   
    // Set a background for menubutton to have a visible look
    getContentPane().setBackground(Color.darkGray);

    menuBar=new JMenuBar();
    menuBar.setBorderPainted(false);
   
    menu=new JMenu("File");

    // It's my style!
    menu.setBorderPainted(false);

    newFile=new JMenuItem("New");
    open=new JMenuItem("Open");
    save=new JMenuItem("Save");
    saveas=new JMenuItem("Save As");
    exit=new JMenuItem("Exit");

    menu.add(newFile);
    menu.add(open);
    menu.add(save);
    menu.add(saveas);
    menu.add(exit);
   
    // Add menu to menubar
    menuBar.add(menu);

    // Add(don't set) menubar to frame
    add(menuBar);

    // Make frame maximized for a good look
        //setExtendedState(MAXIMIZED_BOTH);

    // or pack
    pack();   
    }
    public static void main(String args[])
    {
    new MenuButton();
    }

}

javax.swing.*: Contains JFrame, JMenuBar, JMenu, JMenuItem.
java.awt.*: Contains the layout classes. FlowLayout here.
borderPainted(): Make the border painted false. It is your wish!
