CSPC 120B Assignment #2
Due Friday, September 21, by 4:00 p.m.


Your friend is going into the landscape business and specializes in building circular gardens surrounded by morterless brick walks. He wants you to write a program that will help him estimate the materials needed to build a walk. He gives you the following information:

Your program should take as input the diameter of the garden and the width of the walk and print out the area of the walk and the quantity of bricks and sand needed. See below for details on input and output.

Input and Output

Your program should prompt the user for the following input: Provide the following information as output: All of this should be nicely formatted and labeled. For example, your output might look like this:
Garden size:  12 feet, 3 inches in diameter
Walk width: 3 feet, 3 inches

Total area of the walk:  158.2577 square feet

Materials needed:

  Bricks: 12 straps plus 50 additional bricks 
  Sand: 10286.75 pounds 

Program Requirements

Store the dimensions that the user inputs in integer variables -- the user is providing whole numbers of feet and inches. However, your calculations should be as precise as possible, using floating point (double) values and variables as appropriate to store calculated values. Note that the number of straps and the number of additional bricks should be integers. Minimize the use of literal values in your program; in most cases you should use named constants instead.

Your program must include documentation at the beginning that first gives a description of purpose of the program, then gives your name (using the @author tag). Also include comments before the main method as we have in lab. Be sure to choose good names for variables and constants. Follow the capitalization conventions for variables and constants discussed in class (and in the textbook). Your code should fall into logical sections (e.g., input/several groups of calculations/output), with each section introduced by an explanatory comment (using the // comment style).

After planning your program (drawing a diagram will help!), do the following:

  1. Launch Eclipse
  2. Highlight the Assignments project in the workbench
  3. Create a new package named assign2. (WARNING: Points will be deducted if you do not name your package assign2!)
  4. Create a new class within the package for your source code - don't forget to check the option to include the "main" stub.

What to Turn In

Turn in hardcopy of your program printed from Linux using the print script created in lab 2 (in other words it must be in the two column format with the "Gaudy" header). E-mail the source code to hughes@roanoke.edu. Put cpsc120 assign2 in the subject line.

Academic Integrity Reminder!!! 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.
