Java: submenu in jpopupmenu with separators and shortcut keys that appear?

Question

how do you go about adding submenu's to an existing jpopupmenu?

when you right click the jpopupmenu appears, I want to access submenus under another menu.

how do you add separators in the jpopupmenu? what about shortcut keys?

Below image describes what I want.

Answer 1

For separators, you will need JSeparator, see example here.

For binding a shortcut, you will need to call setMnemonic, see example here.

For sub-menu, simply add a JMenu to an existing JMenu/JPopupMenu as a child, see example here.

Note: links 4-6 are the same one
