Classroom Management Application – Java Swing (EIDD – POA 2025)

This application was developed as part of an Object-Oriented Programming (POA) group project at EIDD.

It provides teachers with a simple and visual tool to manage classroom layouts, track students, add remarks, and take personal notes.

Main Features

Class Management

• Create teachers and their associated classes
• Dedicated interface for each teacher
• Easy navigation between screens

Visual Classroom Layout

• Configure the number of rows (8 tables per row)
• Assign students to tables
• Move students easily using drag-and-drop
• Automatic reset when redesigning the layout

Student Management

• Add students and assign them to a table
• Delete students
• Random student selection
• Student list with absence marking (red text)

Remarks & Notes

• Double-click a student to open their remark panel
• Add free or predefined remarks
• Delete existing remarks
• Dedicated panel for the teacher's personal notes

Automatic Saving

• The entire model (teachers, classes, students, remarks…) is saved in JSON on exit
• Reloaded automatically at application startup

Software Architecture (MVC + Design Patterns)

The project follows the MVC architecture:

• Model: Professeur, Classe, Eleve, Remarque, GestionnaireClasses, Modele
• View: Frame, PanelProf, PanelClasse, PanelRemarque, PanelProfNotes, PanelFond
• Controller: Manages interactions and synchronization between model and view

Design Patterns Used

Pattern	Location	Purpose
MVC	Entire project	Separates logic, data, and UI
Observer (indirect via Swing repainting)	Swing automatically refreshes UI components when the model changes	Provides reactive updates without manually implementing the Observer interface
Factory (partial)	Centralized methods for creating objects	Simplifies object instantiation
Mediator	Controller	Coordinates interactions between UI components

---

Technologies Used

• Java 17
• Swing / AWT for the user interface
• Log4J 2 for logging
• JSON (org.json) for data state persistence with automatic load/save at application start/exit
• JUnit 5 (planned for unit testing)
