Question

If your program does not compile, you will not receive any points!

You will write a program to keep up with a Jewelry store and some of the Inventory (rings/necklaces/earrings) purchased there (The Jewelry store can be real or not) using Object-Oriented Programming (OOP). The important aspect of object-oriented programming is modular development and testing of reusable software modules.

You love selling rings, necklaces, and earrings as well as programming and have decided to open a Jewelry store. To save money you will write your own program to keep up with your inventory and store.

You will need the five classes discussed below:

- An Inventory class, with class attributes of a product type (ring/necklace/or earrings), a description (kind of metal/jewel etc.), and a cost (this is a monetary value). Make sure these variables are safe (inaccessible from outside of this class)

** about the description: The description should be about what the item is made with/of. I.E. Ring: Diamond Promise ring in 10K Rose Gold. NOT ring: mood ring

- A Test_Inventory class, that is a Junit test class for the Inventory class. This should contain at least 7 test methods testing the Constructors (1 for each variable in the non-empty Constructor) and setters.

- You will need a JewelryStore class, with class attributes of your JewelryStore’s name, an Array (size of 10) of Inventory sold at the JewelryStore, and a counter to keep track of how many items are in the array.

- A Test_JewelryStore class, that is a Junit test class for the JewelryStore class. This should contain at least 6 times est methods, again testing the Constructors, setter, and add method (1 for each variable in the method).

- Your P1Driver has a class attribute of a JewelryStore (DO NOT instantiate any Inventory objects in this class). All the data for the JewelryStore and Inventory are to be hard coded (Do Not ask the user for that data) and passed to the appropriate methods.

Your program will need to:

  

- The Junit tests for the two classes should pass.

- Hard code the data for the JewelryStore and Inventory in the

P1Driver.

- Print a welcoming message for your JewelryStore

- Print the name of your JewelryStore and all the Inventory (you must

have at least 6 different kinds of Inventory, 2 of each type, for the JewelryStore), including the Inventory type, description, and cost (be sure to have different costs, don’t make them all $130.00 or something dumb like that), as well as how much inventory your store has.

- Calculate and print the average cost of Inventory sold at the JewelryStore. Be sure that this average cost looks like a normal monetary amount (i.e.: $245.75 and not $245.75425)

- Print a Good-Bye or Thank you message.
