A Console-Based Vehicle Rental Management System built with Java and Object-Oriented Programming.
The application simulates the workflow of a real-world vehicle rental service with dedicated Admin and Customer modules, vehicle inventory management, maintenance tracking, payment simulation, receipt generation, and email notifications.

Vehicle Rental System is a modular Java console application designed to demonstrate practical implementation of Object-Oriented Programming (OOP) concepts through a real-world rental management scenario.
The system allows administrators to manage vehicles, monitor inventory, schedule maintenance, and oversee rental operations, while customers can browse available vehicles, rent them, complete payments, and receive booking confirmations.
The project emphasizes clean class design, modular architecture, and separation of responsibilities, making it an excellent demonstration of Java programming fundamentals applied to a practical use case.
- Secure Admin Login
- Add New Vehicles
- Remove Vehicles
- View Vehicle Inventory
- Send Vehicles for Maintenance
- Complete Maintenance
- Monitor Vehicle Availability
- Browse Available Cars
- Browse Available Bikes
- Browse Available Buses
- Rent Vehicles

- Availability Tracking
- Maintenance Status
- Rental Price Management
- Category-wise Vehicle Listing
- Rental Payment Simulation
- Receipt Generation
- Email Booking Confirmation
- Booking Summary
The following workflow illustrates the overall execution flow of the Vehicle Rental System from user interaction to booking completion.
- User launches the application.
- Selects either the Admin or Customer module.
- Admin manages vehicles, inventory, and maintenance records.
- Customer browses available vehicles by category.
- Customer selects a vehicle and proceeds with the booking.
- Payment is processed through the payment simulation module.
- A rental receipt is generated.
- Booking confirmation is sent via email.
- Vehicle inventory is updated automatically.
The project follows a modular object-oriented architecture where each class is responsible for a specific part of the rental process.
| Module | Responsibility |
|---|---|
| 🚗 Vehicle | Base class representing common vehicle properties and behavior |
| 🚙 Car / Bike / Bus | Specialized vehicle categories using inheritance |
| 👨💼 Admin | Handles inventory management and maintenance operations |
| 👤 Customer | Performs browsing, renting, and returning of vehicles |
| 📦 VehicleInventory | Stores and manages available vehicles |
| 💳 PaymentGateway | Simulates rental payment processing |
| 🧾 ReceiptGenerator | Generates booking receipts |
| 📧 EmailService | Sends booking confirmation emails |
| Controls application flow and user interaction |
| Category | Technologies |
|---|---|
| Programming Language | Java |
| Paradigm | Object-Oriented Programming (OOP) |
| Collections | ArrayList |
| IDE | Eclipse |
| Email Service | JavaMail API |
| Version Control | Git & GitHub |
The project applies core Object-Oriented Programming principles to create a modular and maintainable application.
| Concept | Implementation |
|---|---|
| Encapsulation | Private fields with controlled access through methods |
| Inheritance | Car, Bike, and Bus extend the Vehicle class |
| Polymorphism | Common vehicle operations implemented through inheritance |
| Abstraction | Shared behavior defined within the Vehicle class |
| Composition | Inventory and payment modules collaborate to complete rentals |
| Collections Framework | Vehicle management using ArrayList |
