Assignment Description
 

 

 

 


BevShop (The Data Manager Class)

 

The BevShop offers 3 types of beverages: Coffee, Alcoholic and Smoothie. Beverages can be ordered in 3 different sizes: Small, medium and large. All the beverage types have a base price. In addition there are additional charges depending on the size and specific add-ons for each type of beverage.

 

The BevShop has the following functionality:



·         Create and process orders of different types of beverages

·         Provide information on all the orders 

·         Total amount on a specific order

·         Monthly total number of orders

·         Monthly sale report

Classes
 


Enumerated Type – DAY

Create an enumerated type called DAY.  The valid values will be MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY.

Enumerated Type – SIZE

Create an enumerated type called SIZE.  The valid values will be SMALL, MEDIUM, LARGE.

Enumerated Type – TYPE

Create an enumerated type called TYPE.  The valid values will be COFFEE, SMOOTHIE, ALCOHOL

 

Data Element - Beverage

Create an abstract class called Beverage with:

·         Instance variables for beverage name, beverage type, size, and constant attributes for the base price ($2.0) and size price (additional $1 to go a size up).

·         A parametrized constructor to create a Beverage object given its name, type and  size

·         An abstract methods called calcPrice that calculates and returns the beverage price. 

·         An Overridden  toString method: String representation for Beverage including the name and size

·         An Overridden  equals method: checks equality based on name, type, size of the beverage

·         getters and setters  and any other methods that are needed for your design.  

·         Use finals to represent constants.

 

 

Data Element – subclasses of Beverage

Create the following subclasses of Beverage for the 3 types of beverages: 

 

Coffee

·         Contains additional instance variables of type boolean to indicate if it contains extra shot of coffee (additional cost of 50 cents) and extra syrup (additional cost of 50 cents).   

·         A parametrized constructor  

·         An Overridden  toString method: String representation of Coffee beverage, including the name , size ,  whether it contains extra shot, extra syrup and the price of the coffee

·         An Overridden calcPrice method.

·         An Overridden  equals method: checks equality based on the Beverage class equals method and additional instance variables for this class.

·         getters and setters  and any other methods that are needed for your design.

·         Use finals to represent constants.

Smoothie

·         Contains additional instance variables for number of fruits and boolean variable to indicate if protein powder is added to the beverage. The cost of adding protein is $1.50 and each additional fruit costs 50 cents.

·         A parametrized constructor  

·         An Overridden toString method: String representation of a Smoothie drink including the name , size, whether or not protein is added , number of fruits and the price

·         An Overridden equals method: checks equality based on the Beverage class equals method and additional instance variables for this class.

·         An Overridden calcPrice method.

·         getters and setters  and any other methods that are needed for your design.

·         Use finals to represent constants.

 

Alcohol

·         Contains additional instance variable for weather or not it is offered in the weekend.  The additional cost for drinks offered in the weekend is 60 cents. 

·         A parametrized constructor  

·         An Overridden toString method: String representation of a alcohol drink including the name, size, whether or not beverage is offered in the weekend and the price.

·         An Overridden equals method: checks equality based on the Beverage class equals method and additional instance variables for this class.

·         An Overridden calcPrice method.

·         getters and setters  and any other methods that are needed for your design.

·         Use finals to represent constants.






Data Element – Customer

Create a class to represent a customer.

·         Instance variables for  name and age

·         A parametrized constructor 

·         A Copy constructor  

·         An Overridden  toString method: String representation for Customer including the name and age

·         getters and setters  and any other methods that are needed for your design.  






Data Element – Order 

Create a class to represent an order. This class implements two interfaces: OrderInterface and Comparable.  

·         Instance variables for  order number, order time, order day and customer and a list of beverages within this order

·         A method to generate a random number within the range of 10000 and 90000

·         A parametrized constructor 

·         A method called addNewBeverage that adds a beverage to the order.  This is an overloaded method to add different beverages to the order.  Refer to the interface OrderInterface provided for you,

·         An Overridden toString method: Includes order number, time, day, customer name , customer age and the list of beverages (with information of the beverage).

·         Override the compareTo method to compare this order with another order based on the order number. Returns 0 if this order number is same as another order's order number, 1 if it is greater than another order's order number, -1 if it smaller than another order's order number.

·         getters and setters  and any other methods that are needed for your design.   Note: The getter method for the customer returns a Deep copy of the customer.

·         Refer to provided OrderInterface interface for additional methods.

·          

 

Data Manager – BevShop

Create a class to represent a beverage shop. This class implements BevShopInterface provided to you. 

·         Instance variable for the number of Alcohol drinks ordered for the current order. The current order in process can have at most 3 alcoholic beverages.

·         An instance  list to keep track of orders

·         The minimum age to order alcohol drink is 21

·           time, order day and customer and a list of beverages Order within this order

·          An Overridden toString method: The string representation of all the orders and the total monthly sale.  

·         Refer to provided BevShopInterface interface for additional methods.

 

Data Structure

·         You will be using an Arraylist within your Order to hold beverages of the order and BevShop class to hold orders.

External Documentation

·         Provide a UML diagram with all classes and their relationships.


Testing

There is no GUI provided for this project. To test your project you may (recommended but not required) to create your own driver file for each class as you gradually implement code.

·         Ensure that  BevShopNoGUITest.java produces the following output:

·         Ensure that all the given JUnit tests .java succeed.
