The JMenu component is the basic menu item container that is placed on a JMenuBar

In various places within the different menus, menu separators divide the options into logical sets. Each of the menu options has a mnemonic associated with it to help with keyboard navigation and selection. The mnemonic allows users to make menu selections via the keyboard, for instance, by pressing Alt-F on a Windows platform to open the File menu. A keystroke associated with several options acts as a keyboard accelerator. Unlike the mnemonic, the accelerator can directly activate a menu option, even when the menu option isn't visible. The Options submenu has an icon associated with it.
