Final Project

This assignment demonstrates your understanding of the concepts from the CMIS 141 class.

Before attempting this project, be sure you have completed all of the reading assignments, hands-on
labs, discussions, and assignments to date.

Design a Java application that will read a file containing data related to the US. Crime statistics from
1994-2013. The description of the file is at the end of this file. The application should provide statistical
results on the data including:

a. Population growth in percentages from each consecutive year (e.g. 1994-1995
calculation is ((262803276 – 260327021)/260327021)*100 = 0.9512%, 1995-1996 would
be ((265228572 – 262803276)/262803276)*100 = 0.9229%)

b. Years where the maximum and minimum Murder rates occurred.
c. Years where the maximum and minimum Robbery rates occurred.

The following are some design criteria and specific requirements that need to be addressed:

a. Use command line arguments to send in the name of the US Crime Data file.
b. You should also use Java classes to their full extent to include multiple methods and at

least two classes
c. You are not allowed to modify the Crime.csv Statistic data file included in this

assignment.
d. Use arrays and Java classes to store the data. (Hint: You can and should create a

USCrimeClass to store the fields. You can also have an Array of US Crime Objects.)
e. You should create separate methods for each of the required functionality. (e.g.

getMaxMurderYear() will return the Year where the Murder rate was highest. )
f. A user-friendly and well-organized menu should be used for users to select which data

to return. A sample menu is shown in run example. You are free to enhance your design
and you should add additional menu items and functionality.

g. The menu system should be displayed at the command prompt, and continue to
redisplay after results are returned or until Q is selected. If a user enters an invalid menu
item, the system should redisplay the menu with a prompt asking them to enter a valid
menu selection

h. The application should keep track of the elapsed time (in seconds) between once the
application starts and when the user quits the program. After the program is exited, the
application should provide a prompt thanking the user for trying the US Crime Statistics
program and providing the total time elapsed.

i. Hint: When reading the Crimes file, read one line at a time (See ReadEmail.java) and
then within the loop parse each line into the USCrimeClass fields and then store that
USCrimeClass Object into an array. Note you can use String.split(“,”) to split the CSV line
into a the fields for setting the USCrimeClass Object.

Here is sample run:

java TestUSCrime Crime.csv

The google recommended Java style guide, provided as link in the week 2 content, should be used to
format and document your code. Specifically, the following style guide attributes should be addressed:

 Header comments include filename, author, date and brief purpose of the program.

 In-line comments used to describe major functionality of the code.

 Meaningful variable names and prompts applied.

3

 Class names are written in UpperCamelCase.

 Variable names are written in lowerCamelCase.

 Constant names are in written in All Capitals.



Braces use K&R style.

Submission requirements

Deliverables include all Java files (.java) and a single word (or PDF) document. The Java files should be

named appropriately for your applications. The word (or PDF) document should include screen captures

showing the successful compiling and running of each of the test cases. Each screen capture should be

properly labeled clearly indicated what the screen capture represents. The test cases table should be

included in your word or PDF document and properly labeled as well.

Submit your files to the Final Project area no later than the due date listed in your LEO classroom. You

should include your name and FP in your word (or PDF) file submitted (e.g. firstnamelastnameFP x or

firstnamelastnameFP )

Grading Rubric:

The following grading rubric will be used to determine your grade:

US Crimes Data Description:

The attached Comma delimited file, named Crime.csv contains US Crime data from 1994 – 2013. The
first line in the file contains the field names. (Note: Do not modify this file in anyway. You should use it
as is for input for your application)

The US Crime data were obtained from this Web Site:
