Question

HOMEWORK PROJECT #1 – SHOPPING CART

Part I.

Create two files to submit:

• ItemToPurchase.java – Class Definition
• ShoppingCartPrinter.java – Contains main() method

1. Build the ItemToPurchase class with the following specifications:

Specifications	Description
ItemToPurchase(itemName)	itemName – The name will be a String datatype and Initialized in default constructor to “none”.
ItemToPurchase(itemPrice)	itemPrice – The price will be integer datatype and Initialized in default constructor to 0.
ItemToPurchase(itemQuantity)	itemQuantity – The quantity will be integer datatype Initialized in default constructor to 0.
Public Member methods	Use of Public member methods (mutators & accessors) setName() & getName() setPrice() & getPrice() setQuantity() & getQuantity()

2. In main method of the driver (ShoppingCartPrinter.java) prompt the user for two items and create two objects of the ItemToPurchase class.

         Your output should look like this:

Item 1

Enter the item name:

Chocolate Chips

Enter the item price:

3

Enter the item quantity:

1

Item 2

3. Add the costs of the two items together and output the total cost.

Output Example:

TOTAL COST

Chocolate Chips 1 @ $3 = $3

Bottled Water 10 @ $1 = $10

Total: $13
