Vehicle Management System - Java Project-1

🎯 Objective

Design a simple Vehicle Management System in Java demonstrating key OOP concepts such as:

• Encapsulation
• Inheritance
• Method Overriding
• Upcasting
• Downcasting

---

✅ Requirements

1. 🔒 Encapsulation

• Create a base class Vehicle with private fields:
  • brand (String)
  • speed (int)
• Provide public getter and setter methods for these fields.

---

2. 🧬 Inheritance

Create two subclasses extending the Vehicle class:

• Car

  • Additional field: fuelType (String)

• Bike

  • Additional field: engineCC (int)

---

3. 🔁 Method Overriding

• Override the showDetails() method in both Car and Bike classes to provide specific vehicle details.

---

4. 🔼🔽 Upcasting and Downcasting

• Upcasting:
  Assign Car and Bike objects to Vehicle type references.

• Downcasting:
  Convert Vehicle references back to Car and Bike to access subclass-specific properties.
