KXO151 Programming & Problem Solving
AIEN-SHOU - 2024
Assignment 2
Deadline for Submission: 9PM (Shanghai) Wednesday, Week 8, 17 April 2024
Maximum Marks Available:  15 (15% of the total assessment for KXO151)
Submission: Via  MyLO
NOTE: All assignments will be checked for plagiarism by  a specialist Java program that checks 
your  assignment  against  other  student’s  assignments  as  well  as  the  Internet  (including  help 
sites). 
Assignment Type: Individual
Requirements:
PLEASE NOTE: This assignment is to be completed by Students individually. If you need help, please 
look  at  the  textbook or  ask  your  lecturer.  Students  who  have  been  working  through  the  tutorial 
exercises should not have much difficulty in completing this assignment.
PLEASE NOTE: The submitted Java code must be able to be compiled from the command line using 
Javac the Java programming language compiler command, or from a basic editor such as jGrasp. Be 
aware that development programs such as Eclipse often use features only available when run using 
their system, meaning that their code may not run on a system without their development program. 
Programs that do not run from the command line using javac (to compile) and java (to run) because 
of a missing development program feature will fail the assignment.  
You are required to perform the following tasks:
Write  a  Java  application  program  named  Asst2.java  which  implements  a  simple  'Healthcheck' 
program. The details (specifications) of this task are given below. Note that the correctness marks 
you receive for your program will depend on how well it matches this specification. If you decide to 
implement something that is more elaborate than specified, you  should understand that:
• There will be no marks awarded for the elaborations you have designed and penalties may 
be applied for confusing/extraneous code.
• Your program MUST STILL meet the basic specifications given below.
The program is to implement a simple ' Healthcheck’ program. The user will be asked four questions 
about themselves:
• Their Weight (in kilograms), (to be stored in an int variable).
• Systolic blood pressure (in mmHg), (to be stored in an int variable).
• Diastolic blood pressure (in mmHg), (to be stored in an int variable).
• Heart rate (in beats per minute), (to be stored in an int variable).
The answers  to  these questions will be  used  to generate a 'Health check'  for  the user,  this  will be 
displayed on the screen.
Specifications of the Program
Page 2 of 9
Prompt the user for the 4 pieces of information about themselves (see above) and store the answers 
in the program. There is no need to check whether the answers are reasonable - that is, if the user 
enters 1000 for their age, 500 for their systolic or diastolic blood pressure, -and 10 for their heart 
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  display a  summary  of  the  health 
metrics entered by the user.
2. The program should categorize the user's blood pressure based on the entered systolic and 
diastolic readings. Blood pressure categories should include:
Low Blood Pressure (Hypotension):
If the systolic blood pressure is less than 90 mmHg AND the diastolic blood pressure is less 
than 60 mmHg, it indicates low blood pressure.
Normal Blood Pressure:
If the systolic blood pressure is between 90 and 120 mmHg AND the  diastolic blood pressure 
is between 60 and 80 mmHg, it indicates normal blood pressure.
Elevated Blood Pressure (Hypertension Stage 1):
If the systolic blood pressure is between 120 and 129 mmHg AND the diastolic blood pressure 
is between 60 and 80 mmHg, it indicates elevated blood pressure, which is the first stage of 
hypertension.
High Blood Pressure (Hypertension Stage 2):
If the systolic blood pressure is between 130 and 139 mmHg OR the diastolic blood pressure 
is between 80 and 89 mmHg, it indicates high blood pressure, which is the second stage of 
hypertension.
Hypertensive Crisis:
If the systolic blood pressure is 140 mmHg or higher OR the diastolic blood pressure is 90 
mmHg or higher, it indicates a hypertensive crisis, requiring immediate medical attention.
3. The program should provide feedback on the user's heart rate, considering normal resting 
heart rate ranges.
Heart Rate Lower Than Normal Resting Heart Rate:
If the heart rate is less than 60 beats per minute (bpm), it indicates that the heart rate is 
lower than the normal resting heart rate. This could be indicative of bradycardia or other 
underlying health conditions where the heart beats slower than usual.
Heart Rate Higher Than Normal Resting Heart Rate:
If the heart rate is greater than 100 bpm, it indicates that the heart rate is higher than the 
normal resting heart rate. This could be indicative of tachycardia or other underlying health 
conditions where the heart beats faster than usual.
Heart Rate Within Normal Range:
If the heart rate falls between 60 and 100 bpm (inclusive), it indicates that the heart rate is 
within the normal range for a resting heart rate. This range is generally considered normal 
for most adults at rest.
4. The program should ask the user if they want to monitor their health again after displaying 
the health metrics summary, blood pressure category, and heart rate feedback. If the user 
chooses to monitor their health again, the process should repeat (the questions will then be 
asked again). If the user chooses to do not want to monitor the health again, then program 
should show a message with total number of health checks done in the session. 
A sample output of the program is attached to the end of this document.

Program Style
The program you write for this assignment must be a single class called Asst2 with the code in a file 
called Asst2.java. There should be a single method (the main() method) in this class.
Your  program  should  follow  the  coding  conventions  introduced  in  this  unit and  shown  in  the 
textbook, especially:
• Variable identifiers should start with a lower case letter
• Final variable identifiers should be written all in upper case and should be declared before 
all other variables
• Every if-else statement should have a block of code for both the if part and the else part (if 
used)
• Every loop should have a block of code (if used)
• The program should use final variables as much as possible
• The keyword continue should not be used
• The keyword break should only be used as part of a switch statement (if required)
• Opening and closing braces of a block should be aligned
• All code within a block should be aligned and indented 1 tab stop (approximately 4 spaces) 
from the braces marking this block
Commenting:
• There should be a block of header comment which includes at least
o file name
o your name (in pinyin)
o student UTas id number
o a statement of the purpose of the program
• Each variable declaration should be commented.
• There should be a comment identifying groups of statements that do various parts of the task.
• There should not be a comment stating what every (or nearly every) line of the code does -
as in: 
num1 = num1 + 1; // add 1 to num1
Save the Output 
Run your program entering data via the keyboard and save the output of your program to a text file 
using your UTas student id number as the name of the file, for example, 159900.txt (in jGrasp, right 
mouse-click in the ‘Run I/O’ window and select ‘Save As Text File’).
Important Notes: 
• Changing a few variable names, adding different data and / or adding your name to the top 
of someone else’s code does not make it your own work. See the section on ‘Plagiarism’ below.
• You need to submit 2 files: 
o your  Asst2.java
o a text file containing the output of your program using your UTas id number as the 
name of the file, for example, 159900.txt. 
o See the section on ‘Submission’ below for more information.
• Before you submit your assignment through the KXO151 MyLO website, it is suggested that 
you make sure the final version of your Java program file compiles and runs as expected – do 
Page 4 of 9
not change the names of the java  file – submit it exactly as you last compiled and ran it.
Programs that do not compile and / or run will fail the assignment. If in doubt, you can 
click on the submitted files, download them from MyLO, and check that they are the files you 
think they should be. 
NOTE: The higher marks are reserved for solutions that are highly distinguished from the rest and 
show an understanding and ability to program using Java that is well above the average.

Submission:
Your  completed  solution (your  Asst2.java file,  plus  a  text  file containing  the  output  of  your 
program  using  your  UTas  id  number  as  the  name  of  the  file,  for  example,  159900.txt)  must  be 
submitted by the deadline. Assignments must be submitted electronically via KXO151 MyLO website
as files that can be read by a text editor such as Microsoft Notepad (submit the *.java file - not the 
*.class file). Follow the following steps to create a package for your assignment files and then submit 
your package file:
1.    On  your  computer  desktop,  create  a  new  folder  using  your  name  and  UTAS  ID  number.  For 
example, if you name is Jianwen Chen and your UTAS ID number is 159900, then the new folder must 
be named Jianwen_Chen_159900;
2. Copy your 2 assignment files into the new folder;
3. Use the WinRAR application to compress the new folder and name it as *.rar. For example, Jianwen 
Chen would name it as Jianwen_Chen_111222.rar.
4. Submit your *.rar file to the unit MyLO “Assignments” folder.
5.  If  WinRAR  application  is  not  available  on  your  computer,  try  to  use  a  similar  application  to 
compress the new folder and name it as *.zip, and then submit the *.zip file.
Details of the actual submission procedure are available through the MyLO webpages. 
Students  who  believe  that  this  method  of  submission  is  unsuitable  given  their  personal 
circumstances must make alternative arrangements with their Lecturer prior to the submission date. 
Extensions will only be granted under exceptional conditions, and must be requested with adequate 
notice on the Request for Extension forms.
In submitting your assignment you are agreeing that you have read the ‘Plagiarism’ section below, 
and that your assignment submission complies with the assignment requirement that it is your own 
work.

Note The High Distinction grade is reserved  for solutions  that  fully meet  the requirements & are highly distinguished  from 
other assignments by their high-quality work & their attention to detail (usually only 10% of students).
PLEASE NOTE: The assignment will receive a single composite mark. The assignment will be accessed 
from the point of view of the requirements: “Does it meet the requirements, and how well does it do 
it?”  Where there is some inconsistency in that the work does not completely match every sub-criteria 
within a particular criteria, then the grade reflects the value of the work ‘on average’.
