• Please remember, tutors and other students are not allowed to view your work and you are not allowed to view other student’s work.
• Students that submit code that does not compile will receive no credit for this assignment.
• Programming takes a lot of time.  Please start immediately.
• I have set up RSS feeds to monitor your commits.  Commit often and early. Use meaningful commit messages.  If you want me to look at your code, include @erimcg in your commit message.

Create the following classes:

Item

• Include the following fields.
  • name (String)
  • cost (double)
• Include a constructor that initializes all of the fields.
• Include getter methods.

OrderLine

• Include the following fields.
  • item (Item)
  • quantity (int)
• Include a constructor that has the following parameters: name (String), item cost (double), and quantity (int).
• Include getter methods.

Order

• Include the following fields:
  • orderLines (OrderLine[10]) which holds an Array of no more than 10 OrderLine objects.
  • count (int) which is initialized to zero and holds the number of OrderLine objects in the array.
• No constructor is included.
• Include a method name addItem that takes as a parameter an OrderLine object and inserts it into the orderLines array.
• Include a method named printOrder that iterates over the orderLines array and for each OrderLine object prints on a separate line the item name, item cost, and quantity.

Driver

• The driver does the following:
  • Creates a new Order object.
  • In a continuous loop:
    • Displays the following menu:
      1. Add Item
      2. Print Order
      3. Exit
    • Asks the user to enter a menu number.
    • Reads the menu number.
    • If the user enters 1, the program asks the user for an item name, item cost, and quantity and retrieves the data.  It then creates a new OrderLine object with the data and passes it to the Order object’s addItem method.
    • If the user enters 2, the program calls the Order object’s printOrder method.
