CPSC 120 -- Assignment #1

Humanitarian Aid Shipment
Due Friday, September 23, 2011 by 4 p.m.

The program should compute the number of drums that the organization can ship (as described below) and the total cost of shipping the container.

Input to the program will be:

• the dimensions (diameter and height) of a drum (in inches)
• the weight (in pounds) of one cubic foot of the commodity to be shipped

Output Your output must be nicely formatted and must include the following information (all appropriately labeled):

• The maximum number of drums that will fit in a shipping container
• The maximum number of drums that can be shipped due to the weight limit
• The total number of drums to be shipped (the minimum of the above two quantities)
• The number of cubic feet of the commodity that will be shipped
• The number of cubic feet of filler needed
• The total cost of the shipment

Assumptions: Your calculations should be based on the following assumptions and requirements.

• Calculate the maximum number of drums that will fit in the container using the following assumptions:
  • The drums must be loaded upright in the container. That is, the value entered as the height of a drum will determine how many can be stacked up in the container.
  • To figure out the maximum number of drums that will fit in the container assume they will be loaded in a rectangular pattern along the floor of the container. That is, each row will have the same number of drums as will each column.
• It is possible that loading the maximum number of drums that fit will exceed the weight limit of the container so you must compute the maximum number of drums that can be in the container based on weight. To do this you need to do the following:
  • Compute the weight of the commodity in each drum (remember that you need to find the volume of a drum to do this).
  • Then figure out how many drums can be shipped so the maximum weight for the container is not exceeded.
• The number of drums that the organization can ship is the minimum of the number that will fit in the container and the number that can be shipped without exceeding the weight limit. There is a method in the Math library that will find the minimum of two values for you.
• Once you have figured out how many drums will be shipped you need to compute the number of cubic feet of space the drums will take up and the number of cubic feet of extra space (not occupied by the drums).
• Finally compute the cost based on the number of drums and the amount of filler needed for the extra space.

Sample Output (NOTE: This shows the prompts and input of 24 (inches) for the diameter of the drum, 34.5 (inches) for the height of the drum, and 60 for the weight per cubic foot of the commodity)

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!!
• See the following code conventions for more detail about formatting and documenting your program.
• Warning: A program that doesn't compile receives almost no credit no matter how small the error.
• Optional (Extra Credit): Use the formatting objects from Chapter 3 to format the numbers (especially the dollar amounts) so they look better.

Submit to Inquire: A zip file containing your program.

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.
