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. The classes you should design are: The ParkedCar Class: This class should simulate a parked car. The class's responsibilities are 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 To know the number of minutes of parking time that has been purchased The Parking Ticket Class: This class should simulate a parking ticket. The class's responsibilities are: 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 egally parked, plus $10 for every additional hour or part of an hour that the car is egally 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: To know the police officer's name and badge number To examine a ParkedCar object and a ParkingMeter object, and determine whether the cars time has expired To issue a parking ticket (generate a ParkingTicket object) if the cars time has expired Write a program that demonstrates how these classes Collaborate.Explanation / Answer
/**Test java class ParkingCarDemo that tests the classes
* Policeoffice, parkingticket,parkingmeter and parkedcar*/
//ParkingCarDemo.java

//Create an instance of ParkedCar class with parking minutes 40

"ABCXYZ", 40);
//create an instance of ParkingMeter with purchase minutes 50
ParkingMeter meter = new ParkingMeter(50);
//Create an intance of PoliceOfficer
PoliceOfficer officerMiller = new PoliceOfficer
("Mathew", 070);
//parking office search for car and its meter to raise a ticket
ParkingTicket ticket = officerMiller.search(car, meter);
System.out.println("For car , "+car.toString());
//checking if ticket is not null
