Question

Parking Ticket simulator For this assignment you will design a set of classes that work together to simulate a police officer issuing a parking ticket. You should design the following classes:

• The ParkedCar Class: This class should simulate a parked car. The class’s responsibili-ties are as follows: – To know the car’s make, model, color, license number, and the number of minutes that the car has been parked.

• The ParkingMeter Class: This class should simulate a parking meter. The class’s only responsibility is as follows: – To know the number of minutes of parking time that has been purchased.

• The ParkingTicket Class: This class should simulate a parking ticket. The class’s responsibilities are as follows:

– To report the make, model, color, and license number of the illegally parked car

– To report the amount of the fine, which is $25 for the first hour or part of an hour that the car is illegally parked, plus $10 for every additional hour or part of an hour that the car is illegally parked

– To report the name and badge number of the police officer issuing the ticket

• The PoliceOfficer Class: This class should simulate a police officer inspecting parked cars. The class’s responsibilities are as follows:

– To know the police officer’s name and badge number

– To examine a ParkedCar object and a ParkingMeter object, and determine whether the car’s time has expired

– To issue a parking ticket (generate a ParkingTicket object) if the car’s time has expired Write a program that demonstrates how these classes collaborate.

Requirements:

No data must be collected from the user from inside the class constructor or any other methods. Data must be collected outside the class(perhaps in the main) and can be passed into the object through constructors. This applies to Car, ParkingTicket, PoliceOfficer, ParkingMeter and all other classes.

For any constructor, pass only information that is needed to initialize the objects of that class. For example, when you create police officer object, pass only police office information to build the object, not car, or parking meter information.
