PART 1
Part 1 demonstrates inheritance.
Your Pizza Shop expands and now handles delivery orders and sit down orders in a restaurant setting. There are differences in a SeatedPizzaOrder and a DeliveryPizzaOrder. These are more specialized versions of the PizzaOrders you have been creating all along and you decide to write a program that handles them the same as much as possible and reuses the code of a general PizzaOrder class as much as possible to demonstrate inheritance.

Create a PizzaOrder Class. This class should have the following properties (and their underlying private variables): Size {of type int}, Toppings {of type String}, Price {of type Decimal}. Make a full constructor for the class that takes all three values, and a default constructor that initializes the basic pizza as a 12 inch cheese pizza for $8. Make sure to include validation in your Size and Price properties and constructor to prevent a change to Size that would be less than 12 or greater than 16, and prevent a change to Price that would be less than 0.

Create a class that inherits from your PizzaOrder class called SeatedPizzaOrder. SeatedPizzaOrder has the three data values that any PizzaOrder has (size, toppings, and price) but also has a tablenumber (of type integer) and serverName (of type string) which allows you to track where the pizza is going and who took the order in the restaurant
Create a class that inherits from your PizzaOrder class called DeliveryPizzaOrder. DeliveryPizzaOrder has the three data values that any PizzaOrder has (size, toppings, and price) but also has a driverName (of type string) which allows you to track who is delivering the pizza.

Create a GUI with controls of your choosing or a console class with a main in it. The choice is up to you to create objects of each and test them. This program should allow the user to enter in the values for a SeatedPizzaOrder and the values for a DeliveryPizzaOrder, and after creating an object of each one, it should displays their values (from the created objects) for the user.

_______ END PART 1 ________________________

PART 2
Part 2 is demonstrating polymorphism with classes of different types in an array being processed by a loop.

This program will demonstrate polymorphism and builds on your assignment 1 program. It will allow an array of PizzaOrders of both subclasses….and handle the bills for all of them to be paid all at once polymorphically.

Copy your PizzaOrder, SeatedPizzaOrder, and DeliveryPizzaOrder classes from PART1 into a new project for a C# XXXXX with a GUI.

Change your PizzaOrder from the PART 1 to be an abstract class. Make sure it has an abstract message called printBill().

Change your SeatedPizzaOrder class. Make sure it overrides the printBill() method to return a string with all of the information on the bill along with 10% added to the price.

Change your DeliveryPizzaOrder class. Make sure it overrides the printBill() method to return a string with all of the information on the bill along with $4 added to the price as a delivery fee.

Make a GUI program (with controls of your choosing) that has an array of 4 PizzaOrders in it. Include a checkbox (or radio buttons if you prefer) on the form to control whether it is a DeliveryPizzaOrder or not. Include all the screen controls needed to get the information from the user for either type of order and have a button to allow the user to add a PizzaOrder to the array of either type based on the users choice.

Finally, make sure the GUI include controls to allow the user to see the 4 PizzaOrders bills using printBill() polymorphically once they are all entered. Like a button to call it for the array in a loop, which takes the output from printBill() and adds it to a listbbox for each of them in turn as the loop calls it.

_______________END PART 2___________________

[Note: Using 4 orders because having exactly 4 means we can enter exactly the set number and prevent null reference exceptions and still use a loop with a counter. We could have a larger array and check for null values to see where there are no orders, or use an ArrayList or other collection in a real world setting. Having a set number simplifies this program and avoids the null reference error in testing..]

Assignment Instructions

Instructions:

* Make sure you go to this week’s chapter lesson for more guidance. 

This assignment involves using arrays and the Math method. Random numbers can be generated using the Math.random() method returning a double type number between 0.0 and 1.0. The Math.ceil() method can be used to round numbers up in a range from 1 to 10.

Writer a program using Math.random() and Math.ceil() to generate a series of four random numbers within a range from 1 to 99 which can be used as selections in a lottery numbers of that range. 

Save the code in jGRASP, then save it in c:myjava and run it.

Payroll Lab

You will be taking in a file (payroll.txt) which details a number of departments (at least 1) and in each department are a set of employees (each department will have at least 1 employee or it would not appear on the payroll sheet). Your job is to read the file in separate out each employee and calculate the total values (hours, salary, number of employees) for each department and in each category (F1, F2, F3, F4). In your final submission please include the .cpp file which should work for any kind of payroll file I supply (which will naturally match the format of the examples below). Be sure to indicate in your submission text if you have attempted any of the bonus points .

An example file:

The IT Department
Bill 8 7 8 9 7 F1
Bob 205103 0.08 F3
Betty 8 8 7 8 8 F2
Brandon 10 10 9 6 9 F2
Brad 9 8 10 9 9 4 1 F4

The Sales Department
Kyle 88840 0.105 F3
Tyler 105203 0.085 F3

Mark 98103 0.115 F3
Jill 8 8 8 8 8 F2

Frank 106101 0.095 F3

Mark 76881 0.091 F3

Anika 8 8 8 8 8 F2

Marta 1 0 0 5 2 F1
Kent 9 8 9 9 9 0 0 F4
EOF

Last in the row after the hours comes the pay grade (F1, F2, F3, F4). The number of hours recorded is based on the pay grade of the employee. F1 and F2s will have 5 numbers for their hours. F3s are commission based where a sales amount and a commission percentage is given. F3s are also assumed to work 30 hours if their commission is 10% or below and 40 hours if their commission is above 10%. F4s will have 7 numbers (as they are on-call during the weekend). Each of the pay grades will also have different pay calculations which are as follows:

F1 = The total number of hours * 11.25
F2 = (The total number of hours – 35) * 18.95 + 400
F3 = The total sales amount * the commission rate
F4 = The first 5 hourly totals * 22.55 + Any weekend hourly totals (the last 2) * 48.75

Your output to the screen should start with the department name, followed by the total pay for all of the employees, then the total number of hours, and the total number of employees. After that you should have a breakdown of each category of employee: F1 total pay and total hours, F2 total pay and total hours…

Each department will have at least 1 employee and each department will contain the word “Department.”

Before coding your solution, take the time to design the program. What are the possible things that the file can have that you need to anticipate? What are the actions that you need to take (read the file, add up hours…)? Are those actions things that could be placed in separate functions? What about the function – can you guess some of the things that will happen? Such as, using substring to pull out part of a line in the file maybe using stoi to convert a string to an integer to add it to the total or creating variables to hold the employee type you find before passing it to another function. Finally, how are these functions called, what is the order and what information is passed to and from?

The requirements analysis phase is an essential part of a system development methodology. According to the FAST methodology, which stake-holders typically participate in this phase? What is the primary focus of requirements analysis? What is not the focus? How should each pro-posed requirement be evaluated? What critical error must be avoided? 

MCROY AEROSPACE

McRoy Aerospace was a highly profitable company building cargo planes and refueling tankers for the armed forces. It had been doing this for more than fifty years and was highly successful. But because of a downturn in the government’s spending on these types of planes, McRoy decided to enter the commercial aviation aircraft business, specifically wide-body planes that would seat up to 400 passengers, and compete head on with Boeing and Airbus Industries.

During the design phase, McRoy found that the majority of the commercial airlines would consider purchasing its plane provided that the costs were lower than the other aircraft manufacturers. While the actual purchase price of the plane was a consideration for the buyers, the greater interest was in the life-cycle cost of maintaining the operational readiness of the aircraft, specifically the maintenance costs. 

Operations and support costs were a considerable expense and maintenance requirements were regulated by the government for safety reasons. The airlines make money when the planes are in the air rather than sitting in a maintenance hangar. Each maintenance depot maintained an inventory of spare parts so that, if a part did not function properly, the part could be removed and replaced with a new part. The damaged part would be sent to the manufacturer for repairs or replacement. Inventory costs could be significant but were considered a necessary expense to keep the planes flying. 

One of the issues facing McRoy was the mechanisms for the eight doors on the aircraft. Each pair of doors had their own mechanisms which appeared to be restricted by their location in the plane. If McRoy could come up with a single design mechanism for all four pairs of doors, it would significantly lower the inventory costs for the airlines as well as the necessity to train mechanics on one set of mechanisms rather than four. On the cargo planes and refueling tankers, each pair of doors had a unique mechanism. For commercial aircrafts, finding one design for all doors would be challenging.

Mark Wilson, One of the department managers at McRoy’s design center, assigned Jack, the best person he could think of to work on this extremely challenging project. If anyone could accomplish it, it was Jack. If Jack could not do it, Mark sincerely believed it could not be done. 

The successful completion of this project would be seen as a value-added opportunity for McRoy’s customers and could make a tremendous difference from a cost and efficiency standpoint. McRoy would be seen as an industry leader in life-cycle costing, and this could make the difference in getting buyers to purchase commercial planes from McRoy Aerospace. 

The project was to design an opening/closing mechanism that was the same for all of the doors. Until now, each door could have a different set of open/close mechanisms, which made the design, manufacturing, maintenance, and installation processes more complex, cumbersome, and costly. 

Without a doubt, Jack was the best—and probably the only—person to make this happen even though the equipment engineers and designers all agreed that it could not be done. Mark put all of his cards on the table when he presented the challenge to Jack. He told him wholeheartedly that his only hope was for Jack to take on this project and explore it from every possible, out-of-the-box angle he could think of. But Jack said right off the bat that this may not be possible. Mark was not happy hearing Jack say this right away, but he knew Jack would do his best.

Jack spent two months looking at the problem and simply could not come up with the solution needed. Jack decided to inform Mark that a solution was not possible. Both Jack and Mark were disappointed that a solution could not be found.

“I know you’re the best, Jack,” stated Mark. “I can’t imagine anyone else even coming close to solving this critical problem. I know you put forth your best effort and the problem was just too much of a challenge. Thanks for trying. But if I had to choose one of your co-workers to take another look at this project, who might have even half a chance of making it happen? Who would you suggest? I just want to make sure that we have left no stone unturned,” he said rather glumly.

Mark’s words caught Jack by surprise. Jack thought for a moment and you could practically see the wheels turning in his mind. Was Jack thinking about who could take this project on and waste more time trying to find a solution? No, Jack’s wheels were turning on the subject of the challenging problem itself. A glimmer of an idea whisked through his brain and he said, “Can you give me a few days to think about some things, Mark?” he asked pensively.

Mark had to keep the little glimmer of a smile from erupting full force on his face. “Sure, Jack,” he said. “Like I said before, if anyone can do it, it’s you. Take all the time you need.” A few weeks later, the problem was solved and Jack’s reputation rose to even higher heights than before.

QUESTIONS

1. What should Mark have done if Jack still was not able to resolve the problem?

2. Would it make sense for Mark to assign this problem to someone else now, after Jack could not solve the problem the second time around?
