class EmergencyFacility

This class has the following instance variables:

A Random variable randy

A Priority $Q$ ueue of type Patient called waitingQ

An ArrayList of type Patient called processedPatients $-$ may be instantiated in variable declaration or in

the constructor$)$

An array of type Doctor called doctors $($remember this is an array, not an ArrayList$))$

A String variable facilityName

An int variable currentTime set to $0$

It has a single constructor with three parameters: String name, int seed, int numDoctors

It simple sets facilityName to name $($You can do this without calling a mutator$)$

It creates the waitingQ object using a new instance of PatientPriority as the parameter, ensuring

that waitingQ prioritizes according to PatientPriority rules

It creates a Random object called randy based on the seed

It calls createDoctors with numDoctors as the parameter

createDoctors has a single int parameter called numDoctors and a void return

It creates the doctors array with a length equal to the value of numDoctors

For each reference in the array it creates a Doctor $($Remember that the Doctor constructor has no

parameters$)$

openEmergencyFacility has no parameters and a void returm

Note: This starts the clock at time $0$ and revs for $10$ minutes $($i$.$e$.0$ currentT ime $<mn>1</mn><mn>0</mn><mtext></mtext><mi>)</mi>$ of loading

up the line before the EmergencyFacility doors open and service begins. cwrentTime should have

a value of $10$ when this is finished

for $($current Time $=0$; current Time $<mn>1</mn><mn>0</mn>$; current Time$++)/$ This simulates early arriving Patients

Do $10$ times

Generate a random number of type int from $1$ to $20($inclusive meaning all of $1$

through $20$ using randy$)$ and use it below

if the random number is less than $8$

Create and add an UrgentP atient to the waiting $Q$ with the currentTime

else if the random number is less than $16$

Create and add a SeverePatient to the waitingQ with the currentTime

else

Create and add a NominalPatient to the waiting $Q$ with the currentTime

operateEmergencyFacility has a parameter int called durationFor.Arriving and a void retum

Create an int variable end.Arrivals Time and set it equal to the sum of the currentTime and

durationForArriving

Create any necessary temporary variables for this method i$.$e$.$ tempPatient

while the size of processedPatients does not equal the Patient idCounter or the currentTime is less than

the endArrivals Time $($note: all arrivals get processed this way$)$

if the currentTime is less than the endArrivalsTime $/$This simulates arriving Patients until the

office doors close

Do $6$ times

Generate a random number of type int from $1$ to $20($inclusive meaning all of $1$

through $20$ using randy$)$ and use it below

if the random number is less than $7$Create and add an UrgentPatient to the waitingQ with the current Time

else if the random number is less than $14$

Create and add an SeverePatient to the waitingQ with the current Time

else

Create and add an NominalPatient to the waitingQ with the current Time

End of the do loop

$/$Now check on the busy Doctors

for each Doctor referenced in the doctors array

if the Doctor isn't free $($i$.$e$.$ getlsFree returns false$)$

Call decrementTimeRemainingForExam$()$ for this Doctor

if the timeRemainingForExam for this Doctor is $0$

Retrieve the reference to the Patient currently assigned to this

Doctor $($use a tempPatient variable to capture the reference and the

method getAssignedPatient$())$

Add that tempPatient to the processedPatients ArrayList

Call setTotalTimeAtEmergencyFacility for this tempPatient with the

currentTime

Call removeAssignedPatient$()$ for this Doctor

$//$Now Assign Patients to free Doctors. Note: this section must come after the above section

For each Doctor referenced in the doctors array

if isFree is true for the Doctor $($ie$.$ getisFree returns true$)$ and the waiting $Q$ is not

empty

Remove a Patient from the waitingQ $($use a tempPatient variable to capture

the reference$)$

Call setDoctorStart Time for tempPatient with the currentTime

For this Doctor call setAssignedPatient with a reference tempPatient just

removed from the waitingQ

Use randy to help get a number from $10$ to $25$ minutes $($inclusive$)$ calling it

examDuration

Call setExamDuration for the tempPatient with examDuration as the

parameter

Call setTimeRemainingForExam for this Doctor with this examDuration as

the value the parameter

Increment currentTime by $1.$ Note this happens inside the while loop just before looping

End the while $($put in here for clarity of description only

generateEmergencyF acilityResults has a String parameter representing the physical output file and

retums a void $($remember the throws IOException$)$

This method should write data to the output file. efoutput.tst is a sample based on following my

instructions and the interactive input below.

First create a PrintWriter based on the physical o
