Stage 2: Enhance the classes defined in Stage 1 to develop a Cash Register Application

The objective of the second stage is to develop a Cash Register application which will utilize the classes developed in Stage 1.

Stage 2: Task(s)

The programmer will use and extend the classes and methods developed in Stage 1 to develop a Cash Register type of application. This application will declare an enumerated type ‘BabyType’, which will be used in a switch statement to determine which action needs to be taken. Depending on the BabyType, the program should prompt for specific details in order to calculate the price for each item. FOOD Prompt for Name of Food, the Number of Jars and the Price per Dozen of Jars CLOTHES Prompt for Name of Clothes, the number of clothes and price per item TOY Prompt for Name of the Toy, the Number of Toys, the Price of Each and the Price of any Accessories The application should be called ‘BabyShop’, which will prompt the user for items to purchase one at a time. This application will prompt the user for the name of the product. If no name is entered, the application will calculate the total cost of items entered. The application will define three arrays for each BabyType, which can store up to 5 items each. Each derived class will contain a static variable which will store the total BabyType cost and total BabyType tax (if applicable) for that specific BabyType. The CLOTHES and TOYS baby types are taxable at 7%. The FOOD type is non-taxable. As each BabyType item is added, the cost and tax should be added to the individual BabyType static values. The BabyItem superclass will also contain a total cost and total tax static variable that will be shared between all items that were derived from that superclass. As each BabyType item is added, the cost and tax should be added to the BabyItem static values. Upon entering all items, the application should print out a summary of all purchased BabyItem, along with the count, the cost and tax. (See Sample Output) Stage 2: Sample Output Baby Shirt $ 8.98 [Tax: $0.63] 2.00 @ $4.49 Burp Cloth $ 0.75 [Tax: $0.05] 0.50 lbs @ $1.50 Strained Pea $ 1.33 [Tax: $0.09] 4 jars @ $3.99 per Dozen Teething Cookies $ 4.25 [Tax: $0.30] 12 cookies @ $4.25 per Dozen Lego’s $ 2.75 2 toys @ $1.05 + $0.65 Baby Dolls $ 5.29 3 toys @ $1.33 + $1.30 CLOTHES [ 2] Cost: $ 9.73 Tax: $0.68 FOOD [ 2] Cost: $ 5.58 Tax: $0.39 TOYS [ 2] Cost: $ 8.04 ---- -------- ----- Subtotals [ 6] $23.35 $1.07 ======== Total $24.42 Stage 3: Prompt the user for a receipt file name, write the contents of the receipt to the text file. The objective of this third stage is to save the receipt information to a text file. Stage 3: Task(s) The objective of this third stage is to enhance the application developed in stage 2 to prompt for a filename to store the receipt information. Upon entering the receipt, the receipt contents developed in stage 2 will be output to the text file. The application should create a NoItemsEnteredException. The application should create a static method called itemsEntered which returns the total number of items purchased. If there are no items, the method should throw the NoItemsEnteredException.
