A food delivery management application for a catering company, developed for the Fundamental Programming Techniques course // 2nd year, 2nd semester @ Computer Science, TUCN
In the application implemented in Java, the client can order products from the company's menu.
The system has three types of users that log in using a username and a password: administrator, regular employee, and client.
The administrator can:
• Import the initial set of products which will populate the menu from a .csv file.
• Manage the products from the menu: add/delete/modify products and create new products composed of several products (an example of composed product could be named “daily menu 1” composed of a soup, a steak, a garnish, and a dessert).
• Generate reports about the performed orders considering the following criteria:
o time interval of the orders – a report should be generated with the orders performed between a given start hour and a given end hour regardless the date.
o the products ordered more than a specified number of times so far.
o the clients that have ordered more than a specified number of times and the value of the order was higher than a specified amount.
o the products ordered within a specified day with the number of times they have been ordered.
The client can:
• Register and use the registered username and password to log in within the system.
• View the list of products from the menu.
• Search for products based on one or multiple criteria such as keyword (e.g. “soup”), rating, number of calories/proteins/fats/sodium/price.
• Create an order consisting of several products – for each order the date and time will be persisted and a bill will be generated that will list the ordered products and the total price of the order.
The employee is notified each time a new order is performed (using the Observer Design Pattern) by a client so that it can prepare the delivery of the ordered dishes.
- The data from the .csv is read using streams.
- Lambda expressions and stream processing is used for generating the administrator specific reports and for search functionalities.
- The Composite Design Pattern was used for modelling classes MenuItem, BaseProduct and CompositePorduct.
- A bill is generated in a .txt format.
- JavaDoc files can be generated for documenting the functionalities of the application.
- Serialization is used to ensure the data necessary for the application is up to date.
