EcoTrack+

A Java-based desktop application that helps users track their carbon footprint, monitor weekly carbon budget, visualize analytics, and maintain persistent user profiles. The application demonstrates object-oriented principles, Swing GUI, JavaFX charts, file-based storage, and multithreading.

Features

User Authentication

• Login and registration using file-based storage
• Per-user directories containing:
  • credentials.txt
  • profile.txt
  • activity_history.csv
  • badges.txt
• Passwords stored as hashes
• User data is restored automatically on login

Activity Tracking

Supports logging:

• Travel activities (Car, Bus, Train, Bike, Walk)
• Food activities (Veg, Non-Veg, Vegan)
• Energy usage (Electricity consumption)

Each activity updates:

• CO₂ emission calculation
• Weekly carbon budget
• EcoScore
• User history and badges

Analytics Dashboard

Implemented using JavaFX embedded inside Swing:

• Pie chart for emissions by category
• Bar chart for category comparison
• Line chart showing emission trends

Weekly Carbon Budget

• Default weekly limit: 60 kg CO₂
• Visual budget indicator
• Warning levels (High, Medium, Low)
• Automatic weekly reset using a background thread

EcoScore System

Score updates based on emission levels:

• Very low emission → +5
• Low → +3
• Medium → +1
• High → -1

Badge System

Awards badges based on user progress:

• Green Beginner
• Eco Warrior
• Carbon Saver

Badges are restored per user and saved persistently.

Architecture Overview

Model Layer

Contains core business logic:

• Activity classes (Travel, Food, Energy, RestoredActivity)
• CarbonBudget and BudgetExceededException
• EcoScoreEngine and ScoreHistory
• Badge system (Badge, BadgeManager)
• User system (User, UserManager)
• HistoryManager
• Multithreading (BudgetMonitorTask, WeeklyResetThread)

Controller Layer

• ActivityController: handles activities, budget, score, badges, and persistence
• DashboardController: provides analytics data for charts and the dashboard

View Layer

• Swing UI: LoginForm, RegisterForm, Dashboard, AddActivityForm, BadgeViewer
• JavaFXAnalytics: chart visualisation
• SwingFXPanelBridge: integrates JavaFX into Swing

Concepts Demonstrated

This project covers major topics from the Java OOP and Java Programming syllabus:

• Classes, Objects, Inheritance, Polymorphism, Abstraction, Encapsulation
• Abstract classes, Interfaces, Nested classes
• Exception handling (custom and built-in)
• Multithreading (Thread, Runnable, interrupt handling)
• Java I/O (FileReader, FileWriter, BufferedReader, Path API)
• Collections (List, Map, ArrayList, HashMap)
• Generics (List, Map<String, Double>)
• GUI programming (Swing)
• JavaFX chart rendering
