Goals: Review the design recipes, work with inexact numbers, review the design of loops using the accumulator style.
The names of the projects and some of the project files must be exactly the same as specified in the assignment. Failure to do so makes it impossible for the graders to run your submission and results in immediate loss of at least 50% of the homework credit.
Make sure you follow the style guidelines for code indentation.
You will submit this assignment by the deadline using the Web-CAT submission system. We will be practicing its use during the lab next week.
With each homework you will also submit your log file named pairxx.txt where you replace xx with your pair number.
On top of every file you submit you will have the names of both partners, and the pair number.
The .txt file will be the log of your work on this assignment. Each log entry will have data and time, who was present (one or both of the partners) and a short comment decribing what you were working on.
Due Date: Thursday, September 20th, 11:59 pm.
Work out these problems on your own. Save them in an electronic portfolio, so you can show them to your instructor, review them before the exam, use them as a reference when working on the homework assignments.

Here is a data definition in DrRacket:
;; A Pizza is one of
;; -- (make-plain String String)
;; -- (make-fancy Pizza String)
(define-struct (plain crust cheese))
(define-struct (fancy base topping))
Draw the class diagram that represents this data definition.
Convert this data definition into Java.
Include in your examples the following two piza orders:
– a pizza with thin crust, mozarella cheese, and two toppings: mushrooms and olives
– a deep dish pizza with mixed cheese, pepperoni, and onions
Make sure the two sample orders given above are named order1 and order2.
