abstract class Patient implements the Comparable interface for Patient

Has a public static int variable idCounter set to $0.$

Has int instance variables arrivalTimeAtEmergencyFacility, doctorStartTime, waitTime, examDuration,

totalTimeAtEmergencyFacility

Has a String instance variable patient Type

Has a single constructor with a parameter for arrival Time which

Calls setArrivalTimeAtEmergencyFacility with the arrivalTime from the constructor as the

parameter

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

The mutator method for setArrivalTimeAtEmergencyFacility accepts an int parameter and has a void

return

It sets the arrivalTimeAtEmergencyFacility equal to the input parameter value

The mutator method for setExamDuration accepts an int parameter and has a void return

It sets the examDuration equal to the input parameter value

The setDoctorStartTime accepts an int with the doctorStartTime as the parameter and has a void return

It sets the doctorStartTime equal to the input parameter

It sets the waitTime as the difference between the doctorStartTime and the

arrivalTimeAtEmergencyFacility

The setTotalTimeAtEmergencyFacility method accepts an int with the endTime as a parameter and has

a void return

It sets the totalTimeAtEmergencyFacility to the difference between the endTime and the

arrivalTimeAtEmergencyFacility

The setPatientType method accepts a String reference to the patientType as the parameter and has a void

return

It sets patientType to the parameter $($a reference variable$)$

There are the following $3$ abstract methods:

setPatientID has no parameters and a void return

getPatientID has no parameters and returns a String

compareTo has a reference to a Patient as a parameter and returns an int $($this is the method from

Comparable, but it is given a coded body in each of the subclasses, not here. In fact it does not even need

to be stated here$)$class UrgentPatient is a subclass of Patient

Has a String instance variable patientID

Has a single constructor with an int parameter indicating the arrivalTime

Calls super with arrivalTime as the parameter

Calls setPatientType with "URGENT" as the parameter

Calls setPatientID with no parameters

There is a normal accessor getPatientID that overrides the abstract version of this method

setPatientID has no parameters and a void return $-$ this is an override of the abstract method setPatientID

It increments the static variable idCounter declared in Patient

It sets patientID to the concatenation of the patientType, and the Patient.idCounter

Note: a patientID might look like this URGENT $106$

compareTo has a reference to a Patient as a parameter and returns an int $-$ this is an override of the

abstract method in Patient

Returns an int based on a reversal of the natural order for the String patientType. $($i$.$e$.$ URGENT

will precede SEVERE which precedes NOMINAL.$)$

Note: compareTo will be used in PatientPriority

class SeverePatient is a subclass of Patient

Has a String instance variable patientID

Has a single constructor with an int parameter indicating the arrivalTime

Calls super with arrivalTime as the parameter

Calls setPatientType with "SEVERE" as the parameter

Calls setPatientID with no parameters

There is a normal accessor getPatientID that overrides the abstract version of this method

setPatientID has no parameters and a void return $-$ this is an override of the abstract method setPatientID

It increments the static variable idCounter declared in Patient

It sets patientID to the concatenation of the patient Type, and the Patient.idCounter

Note: a patientID might look like this SEVERE $15$

compareTo has a reference to a Patient as a parameter and returns an int $-$ this is an override of the

abstract method in Patient

Returns an int based on a reversal of the natural order for the String patientType. $($i$.$e$.$ URGENT

Has a String instance variable patientID

Has a single constructor with an int parameter indicating the arrivalTime
