class Doctor

Has a static int variable doctorCounter set to $0$

Has the boolean instance variable isFree

Has the int instance variables doctorIDNumber, totalPatientsSeenByDoctor, timeRemainingForExam

Has the reference variable assignedPatient of type Patient

Has a single default constructor

Calls setDoctorIDNumber with no parameters

Calls setIsFree with true as the value of the parameter

There are simple accessor $($getXXX$)$ methods for each of the five instance variables

setDoctorIDNumber has no parameters and a void return

It increments the doctorCounter by $1$

It sets the doctorIDNumber equal to the doctorCounter

setIsFree has a boolean parameter and a void return

It sets isFree to the value of the parameter

setAssignedPatient has a reference to a Patient as the parameter and a void return

It sets the reference variable assignedPatient to the value of the parameter

It calls setIsFree with false as the parameter

removeAssignedPatient has no parameters and returns a reference to the assignedPatient

Create a temporary Patient reference variable tempPatient equal to the current assignedPatient for

this Doctor

Set the assignedPatient variable to null

Call setIsFree with the parameter true

Increment totalPatientsSeenByDoctor by $1$

Return the value in the tempPatient reference variable

set TimeRemainingForExam has an int parameter and a void return

set timeRemainingForExam to the value of the parameter

decrementTimeRemainingForExam has no parameters and a void return

It decrements timeRemainingForExam by $1$

toString has no parameters and returns a String $-($normal override$)$

String should look like this $($of course the numbers will be different$)$

Doctor $17$ examines $21$ patientsclass PatientPriority implements the Comparator interface for Patient

Note: The idea is that an UrgentPatient has higher priority than SeverePatient who has higher priority than

a Nominal.

This class has one method compare with two parameters, both of which are references to Patient objects.

If the two Patients are of the same patientType $($you can use compareTo you wrote for each Patient here$),$

the one who arrived earlier has a higher priority. This means return a negative, $0$ or positive value based

on the difference in the arrivalTimeAtEmergencyFacility between the first and second Patient.

Otherwise use the result of compareTo for the two Patients to obtain the return value
