• Habit Construction: Track and build long-term habits with dedicated tools.
• Google Calendar Sync: Two-way synchronization with your Google Calendar to ensure you never miss a deadline.
• Gamification: Stay motivated with a built-in Leaderboard and User Statistics to track your progress.
• Secure Authentication: Fully functional User Login and Signup system.
• Data Persistence: Reliable local data storage and cloud integration.

Built With

• Language: Java 17
• GUI Framework: Java Swing
• Build Tool: Maven
• APIs: Google Calendar API, Google OAuth Client
• Testing: JUnit 5
• Libraries: org.json, JDatePicker, OkHttp

Architecture & Design

This project serves as a practical implementation of Clean Architecture (Robert C. Martin), ensuring separation of concerns and maintainability.

• Entities: Core business logic and rules, independent of frameworks.
• Use Cases: Application-specific business rules (Interactors).
• Interface Adapters: Controllers, Presenters, and ViewModels that convert data between the use cases and the view.
• Frameworks & Drivers: The outer layer containing the UI (Swing), Database Access, and External APIs.

Design Patterns Utilized

• Builder Pattern: For complex object construction (e.g., AppBuilder).
• Strategy Pattern: For interchangeable algorithms (sorting, filtering).
• Dependency Injection: To decouple components and facilitate testing.
• Observer Pattern: For reactive UI updates.

Credentails Note

Configure Credentials * Obtain OAuth 2.0 Client Credentials (credentials.json) from the Google Cloud Console. * Place the file in src/main/resources/credentials.json. * Note: Ensure this file is listed in your .gitignore to prevent leaking sensitive keys.

Skills & Competencies Demonstrated

• Advanced Java Development: Utilization of modern Java features and strong OOP principles.
• Architectural Design: Strict adherence to Clean Architecture and SOLID principles for scalable software.
• API Integration: Implementation of OAuth 2.0 flows and RESTful integration with Google Services.
• Full-Cycle Development: From requirements and design patterns to implementation, testing, and CI/CD configuration.
• GUI Programming: Creating responsive and interactive desktop applications using Swing.
• Test-Driven Development: Writing unit tests with JUnit/TestNG to ensure code reliability.
