CPSC 120 -- Assignment #2: Bocce
Due Friday, October 15, 2010 by 4 p.m.

Write a program that simulates bocce, an Italian bowling game. The game is played by two teams rolling palm sized balls towards a smaller ball, called the jack. The points of a round of bocce are calculated after both teams roll all of their balls. The team with the ball closest to the jack gets one point for each ball that is closer than the closest ball of the opposing team. The above image shows the team with red balls getting one point becasue it only has one red ball closer to the yellow ball, the jack, then the blue team.

Begin by creating a java file with the appropriate classes and methods to create and display a window. The window should contain a drawing of the jack and four balls, two for each team, as illustrated in the image above. The jack should be centered in the window and the location of the four balls should be randomly generated. It is ok if the balls overlap, but they should not exceed the window dimensions. Finally, calculate and draw how many points were scored and by which team. To calculate the score you must calculate the distance between each ball and the jack. This involves calculating the distance from the center of the jack to the center of each ball. You can calculate this using the Pythagorean theorem, √((x₂-x₁)²+(y₂-y ₁)²).

Requirements:

• You must use meaningful names for variables, constants, and your class. Use Java conventions for case -- constants (declared with final) are all uppercase (with the underscore separating words), variables start with a lowercase letter (but each separate word within the variable starts with a capital), the class name is capitalized. Choosing meaningful names makes your program easier to read and follow.
• You must use constant identifiers where appropriate (there are several constants in the program).
• Use white space (blank lines and blank spaces) in your program to make it easier to read. Separate the sections of the program with blank lines. Indent and align your code properly (emacs helps you do this - it automatically indents in most cases -- if a line isn't indented correctly go to it and press TAB OR select the whole program using CTRL-x, CTRL-p then use ALT-CTRL-\. If TAB doesn't make it indent correctly you probably have a syntax error).
• Document your program. At the top you must have documentation that includes the file name, a brief description of what the program does (this MUST include a list of the input expected and the output the program will produce), the date, and your name. Use inline documentation to document each major section of code. However, don't document every line!!

Warning: A program that does not compile will receive at most 20% on the assignment even if the error is a small one preventing compilation.

Submission

From your assn2 directory, tar your code using the command:

   tar czf username.tgz ClassName.java

To submit your code, copy the tar file containing your code to the directory:

   ~bouchard/cpsc120/assn2

Academic Integrity Reminder!!! Programming assignments are to be your own work. You may get help on the specifics of the assignment from no one except the instructor. You may not show your program to anyone or look at anyone else's program or share ideas with anyone about how to write the program.
