Assignment Description

One of the fundamental requirements of programs is to use data stored in permanent storage such as a hard disk file. Programs must be able to read and write this type of data and use appropriate data structures within the program to work with the data. In this assignment, you will write a program to load and manipulate a data file. The data file can be downloaded from the following link: Unit 4 Sample Data.

The file should not be a comma delimited file and should have the following record structure:

  • FirstName – Character – Size (12)
  • LastName – Character – Size (16)
  • Company – Character – Size (32)
  • Address – Character – Size (32)
  • City – Character – Size (24)
  • County – Character – Size (24)
  • State – Character – Size (2)
  • ZIP – Number – Size (5)
  • Phone – Character – Size (12)
  • Fax – Character – Size (12)
  • Email – Character – Size (32)
  • Web – Character – Size (42)

Step 1: For this assignment, you will write a complete Java console program to load the data file into an ArrayList data structure. Store each line from the file as a separate record in the ArrayList. To read the file, you should use a FileReader wrapped in a BufferedReader. If you create a Java class to contain each record, you will be able to create an object for each record and store the object in the ArrayList. Sorting the data can then be done using another wrapper class that contains the ArrayList and has methods for sorting and output of the data.

Step 2: After the file is loaded into the ArrayList, sort the data in ascending order based on the LastName field, and display the following fields:

  • First name
  • Last name
  • Company

Step 3: Next, sort the data in descending order based on the ZIP field, and display the following fields:

  • First name
  • Last name
  • Company
  • ZIP

Step 4: Display all of the records (and all of the fields) for everyone that is in the state “NY.”

Step 5: The submission should be a single MS Word document with the program source code for the solution and screenshots of the output for the following list:

  1. Sorted data based on last name
  2. Sorted data based on ZIP
  3. Everyone in the state of NY
