Question

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 responsibilities 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. Make the aforementioned classes nested classes within the class containing your main method; only this outermost class can be declared public.

Answer 1

[Note the fine output in the question doesn't match with the question as if we divide 450 by 60 we will get 7.5 hrs so for the first-hour car will be charged $25 and the rest 6.5 hrs car will be charged $70 as part of the hour is also considered so the all total fine will be $95]

if you have any question regarding the program feel free to comment
