Data Formatting

Each of the following appliance types is represented differently in the supplied appliances.txt file.

Each line in the file represents a different appliance and each piece of information for an appliance is separated by a semi-colon.

The first digit of the Item Number indicates the type of the appliance. Each item number is 9 digits long.

Refrigerators

The first digit of the Item Number for refrigerators is 1.

Refrigerators have an Item Number, Brand, Quantity, Wattage, Color, Price, Number of Doors, Height and Width (in inches).

The number of doors value can be either 2 (double doors), 3 (three doors) or 4 (four doors).

Each refrigerator is represented in the appliances.txt file file as follows:

ItemNumber;Brand;Quantity;Wattage;Color;Price;NumberOfDoors;Height;Width

Example:

089360200;Bosch;176;60;black;2000;2;62;29;

Vacuums

Vacuums have an Item Number, Brand, Quantity, Wattage, Color, Price, Grade and Battery Voltage.

The Battery voltage value can be either 18 V (Low) or 24 V (High).

Each vacuum is represented in the appliances.txt file as follows:

ItemNumber;Brand;Quantity;Wattage;Color;Price;Grade;BatteryVoltage

Example:

263788832;Hoover;59;600;black;750;Residential;18;

Microwaves

The first digit of the Item Number for microwaves is 3.

Microwaves have an Item Number, Brand, Quantity, Wattage, Color, Price, Capacity and Room Type.

The room type is where the microwave will be installed, and is either K (kitchen) or W (work site)

Each microwave is represented in the appliances.txt file as follows:

ItemNumber;Brand;Quantity;Wattage;Color;Price;Capacity;RoomType

Example:

383477937;Miele;201;2350;white;179.9;1.8;Kitchen;

Dishwashers

The Sound Rating of the dishwasher can be Qt (Quietest), Qr (Quieter), Qu (Quiet) or M (Moderate).

587065284;Kenwood;74;1010;silver;390;Clean with Steam;Quiet;

Program Guidelines

The fact that the data formatting is different for each type of appliance adds a level of complexity to program development. Creating a class hierarchy is required:

Determine the attributes that are shared between the appliance types and create an Appliance class containing them.

Note: The Appliance class cannot be instantiated and must be a super-class.

Create the following classes such that each one inherits the Appliance class and is located in the programs ProblemDomain folder:

Refrigerator

Vacuum

Microwave

Dishwasher

Ensure that each of these classes has a user-defined constructor that assigns the appropriate attributes.

Override the ToString() method in each one of these classes, so that the data is in a human readable form.

The attributes should be displayed using vertical headers.

Along with the functionality mentioned above, include the following methods in your program:

A method that parses the appliances.txt file into a single list.

The list must be able to contain all appliance types (refrigerator, vacuum, microwave, and dishwasher).

Use the first digit of the item number to determine what valid type of appliance needs to be created (see the Appliance Details section for more information).

A method that allows a customer to purchase an appliance.

The customer is prompted to enter the item number of an appliance. If the entered item number does not match, the program will inform the customer with an error message. If the item number matches, the program checks the appliances availability. If there is an appliance available, the available count will be decremented and the appliance information will be displayed. Otherwise, the customer will be informed the appliance is not available.

A method that prompts the customer to enter a brand. The program performs a case-insensitive search of appliances that have the same brand, and displays them.

A method that prompts a user to enter a number, and the program then displays that number of random appliances. The appliances can be of any type.

When the program exits, implement and call a method that takes the appliances stored in the list and persists them back to the appliances.txt file in the proper format.
