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: Sorted data based on last name Sorted data based on ZIP Everyone in the state of NY Please submit your assignment.For assistance with your assignment, please use your text, Web resources, and all course materials.Grading Rubric Project CriteriaExceeds: 90%–100%Very Good: 80%–89%Meets: 70%–79%Needs Improvement: Below 70%Content (75%) Response covers all topics indicated in the assignment and adds additional content.

Language does not interfere with the communication of ideas and content relevant to the assignment. Errors in grammar, spelling, and sentence structure are present and may distract from the message. Organization is a bit unclear. Format is inconsistent. The writing was of collegiate level with several errors in spelling or grammar.Demonstrates inadequate or partially proficient application of written, visual, or oral skills.

Demonstrates inadequate or partial expression of topic, main idea, and purpose. Audience is often not addressed appropriately. Language often impedes the communication of ideas and content relevant to the assignment. Errors in grammar, spelling, and sentence structure are frequent and often distract from meaning or presentation. Organization is inadequate, confusing, and distracting.

The format is inadequate and obscures meaning. The writing was less than collegiate level with numerous errors in spelling or grammar.

Paper For Above instruction

This project involves developing a comprehensive Java console application to load, process, and display data records from a structured data file. The file, which is provided for download, contains multiple records representing various attributes such as First Name, Last Name, Company, Address, City, County, State, ZIP, Phone, Fax, Email, and Web. Each record has fixed-width fields specified with exact character sizes, deviating from comma-delimited formats. The core objectives include reading the data accurately, storing it efficiently in data structures, and performing sorting and filtering operations for analysis and presentation.

Step 1: Reading Data into Java

Implement a Java program that opens the specified data file and reads each line using a BufferedReader. To optimize data handling, create a Java class (e.g., `Record`) that encapsulates the various fields. Each line from the file should be parsed based on fixed character widths to populate an instance of `Record`. These instances are then stored in an ArrayList, facilitating dynamic data management. A wrapper class, perhaps called `RecordManager`, can hold the ArrayList and include methods for sorting and displaying data conveniently.

Step 2: Sorting by Last Name

Using Java’s built-in Collections.sort() along with a custom comparator, sort the ArrayList in ascending order based on the `LastName` attribute. After sorting, display only the selected fields: First Name, Last Name, and Company, formatted clearly for readability. This step enables users to view an alphabetically ordered list, simplifying inquiries based on last names.

Step 3: Sorting by ZIP in Descending Order

Invert the sorting order to descending based on the ZIP code. The comparator can be modified or a new comparator created to handle reverse order. Once sorted, display First Name, Last Name, Company, and ZIP code for each record, providing insights into geographic distribution and proximity based on ZIP codes.

Step 4: Filtering by State "NY"

Filter the ArrayList to find all records where the `State` field equals "NY". Iterate through the list, select matching records, and display all fields for each. This allows users to focus on data pertinent to New York, useful for regional analysis or contact retrieval.

Step 5: Documentation and Presentation

The final deliverable includes a Word document containing the Java source code encapsulating all functionalities outlined above. Additionally, include screenshots of the output for each of the three sorted and filtered lists: data sorted by last name, data sorted by ZIP, and data for NY residents. Proper documentation facilitates review, replication, and understanding of the code and outputs.

Throughout the implementation, attention should be given to code readability, proper exception handling, and adherence to best practices in Java programming. Utilizing object-oriented principles ensures a modular, maintainable, and scalable solution.
