Design a java application that will read a file containing data

Design a Java application that will read a file containing data related to the US. Crimestatistics from 1994-2013. The description of the file is shown below. The application shouldprovide statistical results on the data including:

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

d. Total percentage change in Motor Vehicle Theft between the years 1998 and 2012.

e. 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:

a. Use command line arguments to send in the name of the US Crime Data file.

b. You are not allowed to modify the Crime.csv Statistic data file included in thisassignment.

c. Use arrays and Java classes to store the data. (Hint: You can and should create aUSCrimeClass to store the fields. You can also have an Array of US Crime Objects.)

d. Your design should include multiple classes to separate the functionality of theapplication.

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

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

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

Here is sample run:

GradingGrading criteria are the same as for the Assignments, and so are not restated here. US Crimes Data Description:The attached Comma delimited file, named Crime.csv contains US Crime data from 1994 – 2013. Thefirst line in the file contains the field names. (Note: Do not modify this file in anyway. You should use itas is for input for your application.) The US Crime data were obtained from this Web Site.Submission requirementsJava Style:• Header comments include filename, author, date, and brief description of the purpose of theprogram• In-line comments as needed to explain any non-obvious code.• Meaningful variable names and user prompts• Class names in UpperCamelCase• Variable names in lowerCamelCase• Constant names in all capitals• Appropriate indentation and use of braces.When submitting your work, upload each Java source file as a separate .java file. Do not include themin any other document. The Java files should be named appropriately for your applications. In yourdocument include:• Your name and assignment number• Your test plan, including the input and expected output. Unless otherwise stated provide threetest cases• Your test results: actual output, and if the test case passed or failed• Screen shots showing successful compiling of the program and running of each test
