Final Project – Java Employee Management System

Description

This Java application allows users to manage employee data with role-based conflict detection and file persistence. It demonstrates key software skills like object-oriented programming, file I/O, and business logic design.

Features

• Add employees with ID, name, roles, and leave balance
• Automatically detects Separation of Duties (SoD) conflicts
• Saves and loads employee data to employees.txt
• Prints a clean console report with flagged conflicts

Data File Format: employees.txt

This file is automatically created by the program and stores employee data in the following CSV format:

ID,Name,Role1|Role2|...,LeaveBalance

Example:

101,Alice,Approver|Processor,5
102,Bob,Viewer,2

---

Sample Console Output

Employee ID: 101, Name: Alice, Roles: [Approver, Processor], Leave Balance: 5
  -> SoD Conflict Detected!
Employee ID: 102, Name: Bob, Roles: [Viewer], Leave Balance: 2
Employee ID: 103, Name: Carlos, Roles: [Processor], Leave Balance: 3
Employee ID: 104, Name: Diana, Roles: [Approver], Leave Balance: 1

---

Example Report Format

This is an optional format you can use for a report.txt or include in a presentation:

=== Employee Report ===

Employee ID: 101
Name: Alice
Roles: Approver, Processor
Leave Balance: 5
⚠ SoD Conflict: Approver + Processor

Employee ID: 102
Name: Bob
Roles: Viewer
Leave Balance: 2
✔ No conflicts

Employee ID: 103
Name: Carlos
Roles: Processor
Leave Balance: 3
✔ No conflicts

Employee ID: 104
Name: Diana
Roles: Approver
Leave Balance: 1
✔ No conflicts

Notes

• employees.txt is generated automatically—no need to create it manually.
• The system flags any SoD (Separation of Duties) conflict where an employee has both "Approver" and "Processor" roles.
• The LeaveRequest.java file is fully implemented and ready for future features (like leave approvals), though it is not currently active in the demo.
