Create Java programs that handle employee data: input, storage, retrieval, and search functionalities, with specifications for file handling, user interaction, and code organization.

Paper For Above instruction

This paper explores the development of a suite of Java applications designed to manage employee data effectively. These applications demonstrate fundamental programming concepts such as file input/output, user interaction, data processing, and code organization. The goal is to create a comprehensive system that allows users to input employee details, store them securely, and retrieve specific records based on user queries.

The first application, WriteEmployeeList.java, facilitates the entry of employee data, including employee ID numbers, first names, and last names. This data is then saved to a file for persistent storage. When executing this program, the user is prompted to enter multiple employee records, including several with identical first names, to facilitate testing of subsequent search functionalities. Proper input validation and user prompts are essential to ensure data integrity.

The second application, DisplaySavedEmployeeList.java, reads the previously saved employee data from the file and displays all records to the user. This module demonstrates efficient file reading techniques, data parsing, and formatted output to enhance readability. It ensures that users can verify the stored data at any time, facilitating transparency and data management.

The third application, DisplaySelectedIDNumbers.java, allows users to input a specific employee ID number and then searches the employee file for a matching record. If a matching ID is found, it displays the employee’s first and last name. If not, it provides an appropriate message indicating that the ID was not found. This functionality highlights the importance of search algorithms and user feedback mechanisms in data-driven applications.

The fourth application, DisplaySelectedFirstNames.java, enables users to enter a first name and retrieves all corresponding employee IDs and last names. If no records match the entered first name, the application informs the user accordingly. This feature demonstrates handling multiple records with the same key value, emphasizing the necessity of iterating through data and managing multiple results.

All four programs should be developed with attention to code readability, reusability, and efficiency. Proper documentation with embedded comments must be included to facilitate understanding and maintenance. The final submission should include all Java source files and any additional files (such as text files) needed for the programs to operate correctly, packaged into a ZIP archive named appropriately.
