Simple Java Car Park Management System

Question

I got a bit rusty in Java, have not program anything like this for ages.I'am trying to create a simple car park manager program and implement following classes Vehicle and the sub classes Car, Van,Motorbike(those extend Vehicle Class. The Car class should hold information about the number of the doors of the car and the color. The Van class should include information about the cargo volume of the van. The class Motorbike should have information about the engine size. The program should allow to add Vehicle to the parking lot, delete the vehicle and print the list of currently parked vehicles and give information if parked vehicles are cars bikes or vans. I have designed all the classes. However i have a problem with the user input on this. User while adding vehicle should be allowed to input car bike or van model, registration plate, the color of the vehicle, also number of doors. And program should print the information when corresponding menu option is chosen. Can you please have a look at the code i have so far, any help will be much appreciated. The problem i have is to get the user to input all the requested information.

public class Vehicle {

    private String carBrand;
    private String regPlate;

    // default constructor
    public Vehicle() {
    }

    // constructor
    public Vehicle(String carBrand, String regPlate) {
        this.carBrand = carBrand;
        this.regPlate = regPlate;
    }

    //getters
    public String getCarBrand() {
        return carBrand;
    }

    public String getRegPlate() {
        return regPlate;
    }

    //setters
    public void setCarBrand(String carBrand) {
        this.carBrand = carBrand;
    }

    public void setColor(String regPlate) {
        this.regPlate = regPlate;
    }
}

        CarParkManager myCarPark = new CarParkManager();

        Scanner input = new Scanner(System.in);

                    System.out.println("List of All Parked Vehicles : ");
                    myCarPark.printParkedVehicleDetails();

                    break;
                }

                case 0: {
                    System.out.println("\nThank you!\n");
                    break;
                }
                default: {
                    System.out.println("Invalid option!\n");
                    break;
                }
            }
        } while (menu != 0);

    }
}

Answer 1

1. Ask user what type of Vehicle they want to create
2. Create the given type of Vehcle
3. Call getDetailsFromUser on the Vehicle

The specific subclass (Van etc) can ask the user what ever questions they need in order to populate themselves.
