Question

(1) Create two files to submit:

• ItemToPurchase.java - Class definition

• ShoppingCartPrinter.java - Contains main() method

Build the ItemToPurchase class with the following specifications:

• Private fields

• String itemName - Initialized in default constructor to "none"

• int itemPrice - Initialized in default constructor to 0

• int itemQuantity - Initialized in default constructor to 0

• Default constructor

• Public member methods (mutators & accessors)

• setName() & getName() (2 pts)

• setPrice() & getPrice() (2 pts)

• setQuantity() & getQuantity() (2 pts)

(2) In main(), prompt the user for two items and create two objects of the ItemToPurchase class. Before prompting for the second item, call scnr.nextLine(); to allow the user to input a new string. (2 pts)

Ex:

Item 1
Enter the item name:
Chocolate Chips
Enter the item price:
3
Enter the item quantity:
1

Item 2
Enter the item name:
Bottled Water
Enter the item price:
1
Enter the item quantity:
10

(3) Add the costs of the two items together and output the total cost. (2 pts)

Ex:

TOTAL COST
Chocolate Chips 1 @ $3 = $3
Bottled Water 10 @ $1 = $10

Total: $13
