CMIS 141 Final Project

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 shown below. The application should provide statistical results on the data including:

1. 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%)
2. Years where the maximum and minimum Murder rates occurred.
3. Years where the maximum and minimum Robbery rates occurred.
4. Total percentage change in Motor Vehicle Theft between the years 1998 and 2012.
5. Two (2) additional crime statistics results you add to enhance the application functionality.

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

1. Use command line arguments to send in the name of the US Crime Data file.
2. You are not allowed to modify the Crime.csv Statistic data file included in this assignment.
3. 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.)
4. Your design should include multiple classes to separate the functionality of the application.
5. You should create separate methods for each of the required functionality. (e.g. getMaxMurderYear() will return the Year where the Murder rate was highest. )
6. 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.
7. 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.
8. 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.

Here is sample run:
java TestUSCrime Crime.csv 1

Submission requirements:
Your deliverables include all Java files (.java) and a single word (or PDF) document. The Java files should be named appropriately for your applications. Your word document should include screen shots showing the successful compiling and running of each application, and a detailed description of the test plan for each application. The test plan should include the input, expected output, actual output and if the test case passed or failed. Submit your files to the Final Project assignment area no later than the due date listed in the calendar.
