Question

Hello I am having trouble putting together the code, here is the assignment requirements to be coded in Java.

I have four days to complete the first phase of this which is simply creating the two interfaces for User called RedBoxUserInterface and RedBoxAdminInterface.

Phase 1 Develop the PurpleBoxUserInterface and PurpleBoxAdminInterface. The interface should provide methods for the requirements below and should include consideration of exception handling. It should also include pre- and post-conditions, parameters and return types on your methods using javadoc documentation as discussed in class.

General capabilities available to users (and defined in PurpleBoxUserInterface) shall include:

Search for movies (see all, Blu-ray vs. DVD, according to genre, new release/date, alphabetically, by name, by critics' score)

Add movie to shopping cart

Remove movie from shopping cart

Remove all movies from shopping cart

See if movie is available

Check out/rent movies in cart, give option to email

Take credit card payment

Return movies

Apply promo code

Similar for games, with types being XBox and PS4

Challenge (optional):

Maintain user account information

Check my account (user’s inventory)

General capabilities available to admins (and defined in PurpleBoxAdminInterface) shall include:

Add movie to inventory

Remove movie from inventory

Change prices (same price for all DVDs, same price for all Blu-ray disks, same price for all games)

Volume discount

Add promo codes

Disable unit

Enable unit

Only one set of interfaces should be submitted per pair of pairs.
