The question and project is in the attached file to make it easier to read but I will also post it right below also.

 

 

Step 1. (Design) Draw a UML class diagram for an ItemToPurchase class with the following specifications:

• private data members (fields)
  • String itemName - Initialized in default constructor to "none"
  • double itemPrice - Initialized in default constructor to 0.0
  • int itemQuantity - Initialized in default constructor to 0
• Default constructor (zero parameter)
• A three-parameter constructor with parameters for item name, price, and quantity
• public member methods (mutators & accessors)
  • setName() & getName()
  • setPrice() & getPrice()
  • setQuantity() & getQuantity()
  • double getSubtotal(): returns itemPrice * itemQuantity
  • void display():  display item information. See sample run for format. Price and subtotal should be displayed with 2 digits after the decimal point.

 

Each setXXX() should have return type void and take a parameter matching the type of the data member it sets.  Each getXXX() should return the corresponding data member.

 

Step 2. Build the ItemToPurchase class. 

 

Step 3. Provide a driver class ShoppingCartPrinter.  In its main(),

• Prompt user for item 1, create an object of the ItemToPurchase class by invoking the default constructor, and then call setXXX() to set the values of its data members. 
• Prompt user for item 2, and create an object of the ItemToPurchase class by invoking the three-parameter constructor    
• Call display() of each item to print item information. 
• Call appropriate methods of the two objects to retrieve subtotal, add together, and output
