csv) containing data related to the US. Crime statistics from 1994-2013.

I need help to design a Java application that will read a file ( Crime.csv) containing data related to the US. Crime statistics from 1994-2013. 

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


  • 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%,

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

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


  • Command line arguments to send in the name of the US Crime Data file
  • use Java classes to their full extent to include multiple methods and at least two classes
  • do not modify Crime.csv Statistic data file 
  • Use arrays and Java classes to store the data. (Hint: USCrimeClass should be created to store the fields. You can also have an Array of US Crime Objects.) 
  • separate methods should be created for each of the required functionality. (e.g. getMaxMurderYear() will return the Year where the Murder rate was highest. ) 
  • 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. 
  • 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
  • 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. 
  • 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
