How do you make menu item (JMenuItem) shortcut?

Question

So i noticed that in awt there is a MenuItem constructor for adding a CTRL + (some key) shortcut, but there is no such constructor for JMenuIte

Answer 1

Example for CTRL + N.

menuItem.setAccelerator(KeyStroke.getKeyStroke('N', Toolkit.getDefaultToolkit ().getMenuShortcutKeyMask()));

Toolkit.getDefaultToolkit ().getMenuShortcutKeyMask() returns control key (ctrl) on Windows and linux, and command key (⌘) on Mac OS.
