Assignment2

DeadlineforSubmission: 9PM(Shanghai)Wednesday,Week8,17 April2024

MaximumMarksAvailable: 15(15%ofthetotalassessmentforKXO151)

Submission: Via MyLO

NOTE: Allassignmentswillbecheckedforplagiarism by a specialist Java program that checks

your  assignment against other  student’s  assignments  as well  as  the  Internet  (including  help

sites).

AssignmentType: Individual

Requirements:

PLEASENOTE: Thisassignment istobecompleted byStudentsindividually.If you need help, please

look at the textbook or ask your  lecturer.  Students  who  have  been working through the tutorial

exercisesshouldnothave much difficulty in completingthisassignment.

PLEASENOTE: Thesubmitted Java codemustbeabletobecompiled from thecommand line using

Javac the Java programminglanguagecompiler command,orfrom a basic editor such asjGrasp.Be

aware that development programs such asEclipse oftenusefeaturesonlyavailablewhen run using

theirsystem,meaningthattheircode may notrunon a system without their development program.

Programs that donotrunfrom thecommand line using javac (to compile) and java (torun)because

of a missing development program feature will failthe assignment.

Youarerequiredto perform the following tasks:

Write  a Java  application program named  Asst2.java  which implements  a  simple 'Healthcheck'

program.Thedetails(specifications) ofthistaskaregivenbelow.Note that thecorrectness marks

youreceiveforyour programwilldependonhowwellitmatchesthisspecification.If you decideto

implement something that is more elaborate than specified, you should understand that:

? Therewillbe nomarksawardedfortheelaborationsyouhavedesignedandpenaltiesmay

beappliedforconfusing/extraneouscode.

? YourprogramMUSTSTILLmeet thebasic specifications given below.

Theprogramistoimplement asimple' Healthcheck’ program.Theuserwillbe askedfour questions

aboutthemselves:

? TheirWeight(inkilograms),(tobestoredinanintvariable).

? Systolicbloodpressure(inmmHg),(tobestoredinanintvariable).

? Diastolicbloodpressure(inmmHg),(tobestoredinanintvariable).

? Heartrate(inbeatsperminute),(tobestoredinanintvariable).

Theanswers to these questions will be used  togeneratea'Healthcheck'  for  the user, this will be

displayedonthescreen.

rate. The program will accept these  values and continue. Do not ask the user for any other

information.

1. After receiving input  from  the  user, the program should displaya  summary  of the health

metricsenteredbytheuser.

2. Theprogramshouldcategorize theuser's bloodpressurebased ontheenteredsystolicand

diastolicreadings.Bloodpressurecategories shouldinclude:

LowBlood Pressure (Hypotension):

Ifthesystolicbloodpressureis lessthan90mmHgAND thediastolicbloodpressureisless

than60mmHg,itindicateslowbloodpressure.

NormalBloodPressure:

Ifthesystolicbloodpressureis between 90and120mmHgAND the diastolic blood pressure

isbetween60and80mmHg,it indicates normal blood pressure.

ElevatedBloodPressure(HypertensionStage1):

Ifthesystolicbloodpressureisbetween120and129mmHgAND thediastolicbloodpressure

isbetween60 and 80 mmHg,it indicates elevated bloodpressure,which isthefirststageof

hypertension.

HighBloodPressure(HypertensionStage2):

Ifthesystolicbloodpressureis between 130 and 139 mmHgORthediastolicblood pressure

isbetween80and89mmHg,it indicates high bloodpressure,which isthesecond stageof

hypertension.
