IT 06 George Madison University Programming defining diagram Exercise

Programming Assignment 5/6Scenario:
IT Estates, a local real estate company has approached you to write a program to keep track of the
homes the company will custom build for new owners. A new owner can request any one of the
following types of homes to be built. Because the real estate company has limited resources, it can only
build up to 29 homes. However, the company does not know how many homes, in total, will be built
because the homes are built on demand.
Home Type
Cottage
Victorian
Tudor Revival
Mansion
Cost
$99,955
$423,699
$777,399
$1,025,999
Create a program for use by the company’s sales team to take orders for new homes to be built. An
order occurs when the user enters a home type by name (e.g. Cottage). Until the user has indicated they
are finished entering home types, continue to prompt the user to enter a home type. You must validate
the home type, providing an error message and re-prompting the user if an invalid home type is
entered. Keep track of the number of homes that will be built for each home type.
Once the user has indicated they are finished entering home types, display a well-formatted report
containing a list of each home type with its associated cost, the number of homes to be built for that
home type, the total cost of all homes that will be built, and the average cost of a home.
Other Requirements:

Your solution must demonstrate the concept of one-dimensional arrays.
Your solution must not use methods other than main. They are not required for this assignment.
Your solution must not import any Java library other than JOptionPane, including
java.util.Arrays.
Your solution must contain appropriate validation. Try to think about what might be considered
appropriate as you are designing your solution beyond what has already been explicitly
provided.
Your solution may not use any functions or language constructs not covered during this
semester’s IT 106 without prior authorization from your instructor, even if you know other
functions or language constructs. We want everyone to be on the same “playing field”,
regardless of previous programming exposure, and get practice with algorithmic design to solve
1
problems (the intent of the course). Using something existing not discussed in class does not
give you as much practice as solving the problem yourself. Doing this may lead to a substantial
grade penalty, a grade of zero, or an Honor Code inquiry. When in doubt, ask!
To Do (Check Blackboard for Due Dates):
Programming Assignment 5: Solution Design
1) Create a defining diagram that shows the input, processing, and output
2) Create a solution algorithm using pseudocode
3) Show testing using the desk checking table method, to include test data, expected results, and a
desk checking table. Make sure your desk checking considers multiple cases including both valid
and invalid test data to prove your algorithm will work in all cases
Upload a Word document containing only items above to Blackboard.

Programming Assignment 6: Solution Implementation
Write a well-documented, efficient Java program that implements the algorithm you identified. Include
appropriate documentation as identified in the documentation expectations document.
Note: You must use the JOptionPane class for input/output. Additionally, if you use System.exit as
shown in the textbook, it may only be used as the absolute last line in the program. You may not use
System.exit, or any variant that exits the program in the middle of the program. The program should be
designed to only exit once the algorithm has finished.
Upload the .java file of the final program to Blackboard. Be careful that you do not submit a .class file
instead of a .java file.
Your program must successfully compile using jGrasp. Partial credit is available. Any final program that
does not compile, for any reason, will receive an automatic zero. Other IDEs often place in additional
code that you are unaware of, doing too much of the work for you. You are strongly discouraged from
using IDEs other than jGrasp.
Grading Criteria
Requirement
Implementation of Java Program, using efficient practices where appropriate, such as the use
of constants, good variable names, no redundant code, etc.
