[SOLVED] CSC7081 Resit -Crime stats system Assignment brief

Crime stats system Assignment brief:

You have been given some code that is currently being developed as part of a Crime Stats application specifically analysing recent Crime in USA cities. Not all the requirements have been implemented. It is your task to implement these and raise the coding standards of all the code.

Create a project solution (named <Your Name><Student Number>Resit e.g. JamesBrown3048614Resit). Create a package named resit. Add StartApp.java to the solution and the crimeUSA.csv. Ensure your name and student number are placed in the Javadoc comments of all the classes you create. The StartApp has been partially written with a menu.

The application will run (start) from the StartApp.java, initially reading in the data from the crimeUSA.csv file and then perform a number of menu driven operations.

Part 1 – Data mapping, storage and read from file – 50%

Using your knowledge of OOP you should add/update the code based on the following:

1. Analyse the data in the crimeUSA.csv and create a class (CityCrime.java) to represent the data in the csv file, include the following …

   I. Each State name should be recoded as its abbreviation as detailed in the supplied StatesAbbreviations.csv file, e.g ALABAMA as AL etc.

   2. Include a method to return as an int the total number of violent crimes (calculated from total of murder, robbery, assault)
   3. Include a method to return as an int the total number of possession crimes (calculated from total of burglary, larceny and car theft
2. Validation rules :

   No field should be empty and no numeric fields should be less than zero. Any records (city stats) that break these rules should not be included and stored in the arraylist in the system (see Part 1 – 4 below).

3. Conduct a unit test for the CityCrimes class.
4. In the StartApp.java class read and store the data in this arraylist :

   public static ArrayList<CityCrime> cityCrimes = new ArrayList<CityCrime>();

When complete compress (zip) the entire Eclipse solution and upload to Resit (Resit assessment) on

CANVAS. Remember to record and then upload a short commentary walk-through of your code with your solution (upload that too

Now : check the uploads to ensure you have submitted the correct files (in the correct area).
