the Class diagram or structure of this question:

Suppose that we have many kind of vehicles: Car, Moto, Truck, and Bicycle. These vehicles share the characteristics: Color, Make, Model, Year, Price, and NumberOfPassengers. The Car and Truck have additional attributes: Engine, NumberOfDoors and VIN (Vehicle Identification). The Moto has additional attributes: Engine and VIN (Vehicle Identification). The Bicycle has an additional attribute: BicycleType (RoadBicycle or MountainBicycle) using an enumeration.

1. Define the hierarchy of products (vehicles).
2. Use the factory method pattern to create the different vehicles.
3. Define the abstract factory pattern associated to the vehicle creation. In this part, you need to create a factory for each kind of vehicles.
4. For the Car, we specialize by creating subclasses for the different kind of cars (SportsCar, LuxuryCar). We define a decorator to add some accessories to the car: MusicSystem, SunRoof, TouchScreen
5. Define a single class VehicleShop representing a shop for selling and buying vehicles. A unique instance can be created for this shop.
6. Define the main class to instantiate the VehicleShop and the other classes to test them.
