Volunteers needed

Question

As a part of our academic curriculum at a graduate college we are conducting an experiment. We need Java programmers to donate a few hours (3 to 4 hours). A small program of about 350 lines needs to be coded. Requirement specification will be provided. Specific set of data about the experiment will be collected.
Those interested may attempt this.
Description
You are to write a Java program that accepts eight integers on the command line. These integers represent the coordinates of four points on the Euclidean plane. The program is to determine if the points define a quadrilateral, and if so, what type of quadrilateral it is. The program will print out the results, as described below, on the standard output device and exit. The details about input and output are given in the following subsections of this document.
The name of your program (the main class) is to be called QuadChecker. You should write the code for all of the geometric classes you need in your solution, rather than use classes from a class library, such as javax.swing.*, etc.
Input
The program accepts exactly eight integers on the command line. These integers represent the coordinates of the four points in the following manner: x1 y1 x2 y2 x3 y 3 x4 y4. This means that the values represent the points (x1, y1), (x2, y2), (x3, y3), (x4, y4).     
Output
The output of the program depends upon the type of quadrilateral, if any, represented by the input. The following table indicates exactly the output strings to be produced for the different possible types of inputs.
1. A rectangle     -- rectangle
2. A square     -- square
3. A parallelogram     -- parallelogram
4. A rhombus     -- rhombus
5. A trapezoid     -- trapezoid
6. A Any other quadrilateral     -- quadrilateral
7. Anything else     -- not a quadrilateral
You may include a new line after your output.
The program must print out only one of the above strings, and it must be the string that is the most constrained value. For example, if the input represented a square, you would print �square� even though the square is also a quadrilateral, rhombus, parallelogram, and rectangle.
Program Files
The Java program should be written so that all classes are in the same package, and the package is at the top level. That means you should not have your files in a package like �myjava.quadrilateral� or something similar. The following examples indicate how the program should be able to be executed. Programs should be compiled using the javac compiler, or one that is completely compatible with javac (i.e., not J++, or J#).
Samples
The following two examples show how the program is expected to work. The first shows the execution of the program when a .jar file is used, and the second shows the execution when the program is executed from the directory
java �classpath ./quadrilateral.jar QuadChecker 0 0 0 1 1 1 1 0Square
>
java �classpath . Quadchecker 0 0 2 2 4 2 2 0parallelogram
Additional Information
The following definitions and formulae may be helpful in creating your program.
Types of Quadrilaterals
The following table of definitions describes the different type of quadrilaterals
Type of quadrilateral     Definition
Parallelogram     Opposite sides are parallel to each other
Rectangle     Four right angles (90 degrees)
Square     Four right angles and all sides the same length
Rhombus     All sides the same length
Trapezoid     Two sides parallel
Quadrilateral     Four sides
Useful Math
To compute the length, l, of a line with endpoints, (x1, y1), (x2, y2):
To compute the slope, m, of a line with endpoints, (x1, y1), (x2, y2):
Two lines are parallel if they have the same slope.
Two lines are perpendicular if the slope of one is the negative reciprocal of the other. For example, if the one line has a slope of � and the other has a slope of -2, the lines are perpendicular.
The following data need to be submitted along with the code.
Before you start
1.     How many months programming experience do you have, for all programming languages? ________
2.     How many months of Java programming experience do you have? ________
3.     How would you rate your Java programming ability (choose one):
     Poor     Fair     Good     Very Good     Excellent
4.     How many lines of Java code would you estimate that you have written? ________
5.     Have you ever used JUnit before?     Yes     No
If yes, for how many months? ________
6.     Have you ever taken a course in calculus and/or analytic geometry?     Yes     No
After you complete the program
1.     What was your development environment (for example, emacs and javac, Eclipse, Jbuilder, etc.)?
2.     Did you use JUnit as a plug-in to your development environment?     Yes     No
3.     What type of training did you receive for this execrise?     Instructor-led     Self-directed
4.     How much time (approximate minutes) did you spend on training for this exercise? ________
5.     Consider the following statement and rate your aggreement or disagreement with it: �I am confident that my program will pass all acceptance tests.� Circle one of the following.
     Strongly disagree          Disagree          Neutral          Agree          Strongly Agree
Time (min.)
Development:     ________
Test:          ________

<sigh>
What depressingly bad timing - I'm just in the process of seeking volunteers for my evaluation too - this kind of topic just makes people cynical.
Oh well. BTW, hopefully you'll recognise my project as being a genuine effort - plus there's 10 dukes per answer on offer ;-)
