Write a JAVA program to store some details of pizzas (menu item number, size, base, extra cheese, extra
garlic), curries (menu item number, size, curry type) and softdrinks (menu item number, size,
flavour, bottle or can) in a single array, with the options of listing all menu items or deleting a
particular menu item.
Your program must continuously prompt the user to choose an option from a list and act on that
option, until the exit option is chosen. (See the sample output below.) If a menu item is not found,
output "Not found" instead of "Done".

You must use inheritance and polymorphism to model your Pizza, Curry and SoftDrink classes (use
those exact class names) as subclasses of the same base class, which forms the basis for the array.

Note: Be very careful to reproduce the output exactly. Copy-and-paste is highly recommended to
avoid minor typographical errors that drive you crazy when submitting online!

Welcome to Great International Food Court
