Menu Bar tutorials

  • A menu provides a space-saving way to let the user choose one of several options.

  • A menu is a common feature of Frame and JFrame windows. There are three components to a menu:

    1. A menu bar, which is attached to the window. The menu bar is typically shown at the top of a window.

    2. A menu, which is attached to the menu bar or another menu. Themenus have a label, and clicking on the label causes the menu to drop down and display its menu items.

    3. A menu item, which is attached to a menu. Selecting a menu item generates an ActionEvent.

  • The AWT classes MenuBar, Menu, and MenuItem are used to create a menu for a Frame.

  • The Swing classes JMenuBar, JMenu, and JMenuItem are used to create a menu for a JFrame.

  • The process of creating menu is similar for both AWT and Swing.

  • Below is the steps for creating menu in and swing:

    1. Instatiate a new JMenuBar object, and attach it to the JFrame using the setJMenuBar() method of the JFrame class.

    2. Instantiate one or more JMenu objects, and add them to the JMenuBar using the add(JMenu menu) method of the JMenuBar class.

    3. Instantiate one or more JMenuItem objects, and add them to a JMenu object using the add(JMenuItem) method of the JMenu class.

  • Below is the program for creating menu in Java:


Example: Java program for creating menu bar

 Sam Madam

//Program name

//Java program for creating menu bar

import javax.swing.*;

public class MenuBar


public static void main(String[] args)


JFrame frame = new JFrame("JMenu Bar");


JMenuBar menubar = new JMenuBar();

JMenu filemenu = new JMenu("File");

filemenu.add(new JSeparator());

JMenu editmenu = new JMenu("Edit");

JMenu exit = new JMenu("Exit");

editmenu.add(new JSeparator());

JMenuItem fileItem1 = new JMenuItem("New");

JMenuItem fileItem2 = new JMenuItem("Open");

JMenuItem fileItem3 = new JMenuItem("Close");

fileItem3.add(new JSeparator());

JMenuItem fileItem4 = new JMenuItem("Save");

JMenuItem editItem1 = new JMenuItem("Cut");

JMenuItem editItem2 = new JMenuItem("Copy");

editItem2.add(new JSeparator());

JMenuItem editItem3 = new JMenuItem("Paste");

JMenuItem editItem4 = new JMenuItem("Insert");
