The system supports both passenger and administrator roles. Administrators can add or remove trips, vehicles, and users, and manage existing data efficiently.

# Features

-User registration and login system
-Bus/flight search functionality
-Seat selection and reservation
-Trip and vehicle management via admin panel
-Modern Java Swing user interface

# Technologies Used

- Java  
- Java Swing  
- Object-Oriented Programming (OOP)  
- Design Patterns (Factory, Singleton, Builder, Prototype)

# Architecture Overview

The project follows a layered architecture with clear separation of concerns:

- Model Layer : Contains data classes that represent core entities such as `User`, `Trip`, `Vehicle`, and `Reservation`.
- Repository : Responsible for storing and retrieving data for each model. Each entity has its own repository (e.g., `TripRepository`, `UserRepository`).
- Service : Handles the application logic and validates data before interacting with the repositories. Services ensure rules and constraints are enforced consistently across the system.
