# Course Recovery System (Java OOP Project)
Overview
The Course Recovery System is a Java-based desktop application developed using Object-Oriented Programming principles. The system manages students who require course recovery plans based on academic eligibility.
The project demonstrates strong implementation of core OOP concepts and multi-role system architecture.
## Key Features
- Multi-role login system (Student, Academic Officer, System Admin)
- Course eligibility checking
- Academic report generation
- Recovery plan creation with milestones
- PDF export functionality
- Email notification system
- GUI-based system using Java Swing
The system uses text files stored in the resources/ directory
to simulate database functionality.
These files manage:
- User accounts
- Course records
- Recovery plans
- Academic reports
## OOP Concepts Implemented
- Encapsulation
- Inheritance (User → Student / AcademicOfficer / SystemAdmin)
- Polymorphism
- Abstraction via Interfaces
- Separation of Concerns (Models, UI, Utils, Auth layers)
## Technologies Used
- Java
- Java Swing (GUI)
- File Handling
- OOP Design Principles
## Project Structure
- models/ → Core data classes
- auth/ → Authentication and user management
- ui/ → GUI components
- utils/ → Helper services (PDF, Email, Reports)
- Java 17
- NetBeans / IntelliJ (or any Java IDE)
This project uses the following external libraries:
- iText PDF
- Jakarta Mail
- Jakarta Activation
If running the project outside the original development environment, you may need to manually add the required JAR files to your project's classpath.
The system uses text files stored inside the Resources folder
located in the project root directory.
Do NOT move or rename the Resources folder,
or the application may fail to locate required data files.
## How To Run
1. Clone repository
2. Open in NetBeans / IntelliJ
3. Run OODJAssignment.java
Use the users.txt file for login information
While the system successfully implements core Object-Oriented Programming concepts and functional requirements, several improvements could enhance the overall quality and user experience:
- Redesign the GUI with improved layout consistency and visual hierarchy
- Implement modern UI frameworks (e.g., JavaFX) instead of basic Swing components
- Improve spacing, alignment, and color scheme for better usability
- Add responsive resizing support
- Refactor file handling to use resource-based loading instead of absolute paths
- Implement proper logging instead of console printing
- Introduce unit testing (JUnit) for core modules
- Improve exception handling with custom exceptions
- Replace text-file storage with a relational database (e.g., MySQL or PostgreSQL)
- Implement DAO pattern for better separation of concerns
- Encrypt stored passwords
- Add role-based access validation
- Improve email configuration security
- Package as an executable JAR
- Add installation guide
- Improve portability across systems
This project focused primarily on demonstrating strong Object-Oriented Programming principles and system structure rather than advanced UI/UX design.
