Using Java...

I need a main menu that has sub menus within it. So for example a menu that has 3 options and an exit program option, and then once you click those options f.e 1 2 or 3 it leads to another menu with more options and also includes an exit option and a return to main menu option within the submenu options.

Also, it would be aprreciated if there were error checks for example if someone enters a string instead of a number. Thanks.
