I love sharing as I learn, especially through stimulating and playful examples. So where objects, classes, and subclasses. For loops, ifs, and variables-they were all right there, at the core of those games. I learned the most fundamental concepts of programming by building interactive fiction exercises. Items.Use class inheritance to define and describe game items in an interactive fiction premise RentalStore class: public interface RentalDAO Someone suggested me that it is possible to do it better than my way. I read some principles of design patterns how to organize application that it will be flexible as much as possible but it seems I need more experience in design area. I don't know how to implement elegant class which will work with rental transactions and will know what items have inventory. In general, I'm not sure in RentalStore class which implements connections to the Inventory and RentalTransactions classes. Inventory and RentalStore class generates some fake records for presentation.Ĭould you please review my app and offer some tips or optimization tricks? If a customer accepts terms than rent transaction is executed successfully.ĭata is not persisted anywhere, data exists in runtime. After the price is calculated for this rent transaction than customer is presented terms where he/she has a choice to accept or reject them. The price for rent calculated automatically based on rent days, video type.
Before the customer rents a video he/she set renting days.Customer can rent only available videos(not rented by someone) with additional option to rent film for bonus points which gathers every time when a customer rents a video (1 point for rent).
Inventory has 3 types of films: Old, New, Regular. Inventory can add/delete/change and receive all videos. The application describes the following tasks: I need some help in working "Video Rental Store" application design optimization.
