The menu component in swing enables you to list various available options. JMenuBar in swing is set on the top area of the Window displaying the GUI for a Java application. A menu bar contains one or more menus with a number of menu items. Swing enables you to add icons, check boxes and radio buttons as menu items. The below figure shows the hirerarchy of menu components that swing supports:

All the JMenu components inherit from the JCOmpoent class of Java. The syntax to create a JMenuBar in Java Swing is:

JMenuBar <JMenuBar_name>=new JMenuBar();

A JMenuBar is set on the top of the container used for containing various components of a GUI. The syntax to set a JMenuBar at the top of the container is:

setJMenuBar(<JMenuBar_name>);

The syntax to create various menu and add the menu to the JMenuBar is:

JMenu <JMenu_name>=new JMenu("name of menu"); <JMenuBar_name>.add(<JMenu_name>);

The syntax to create menu items is:

JMenuItem <JMenuItem_name>=new JMenuItem("name of menu item");

The syntax to create a JMenuItem with icons associated with it is:

JMenuItem <JMenuItem_name>=new JMenuItem("name of menu item",ImageIcon il);

Consider the following example, which shows the use of JMenu to create a menu that displays icons with each menu ites:
