COVID-19 cases have been increased in the last period. As a result, Ministry of Health has
decided to make a simple application to keep track of all citizens and their vaccination status.
In this TMA, it is required to help the Ministry implement the required application.
Requirements:
After a quick meeting with the employee in charge, you got the following information:
It is required to store the whole data in one collection
Each citizen has a unique civil ID number (national number), name and other attributes (add
at least 2 attributes from your choice). In addition, it is required to store information about
all doses taken by the citizen.
For each dose, the following information should be stored: manufacturer, when and where
has been taken, and information about the health professional who gave it.
Each health professional has a unique civil ID number, name, and it is required to store
his/her experience (in years).
Moreover, you have been informed that the following operations happen frequently:
Adding a new citizen to the list
Adding a new dose to a specified citizen
Retrieving number of fully vaccinated persons (who toke at least 2 doses)
Saving all the data into a text file after sorting them according to Civil ID.
Analysis:
Q1: There are common attributes and methods between citizen and health professional. What
is the best choice for designing and writing the codes of these two classes? Explain your
answer.
Q2: Draw a simple class diagram showing only relationships between the classes.
Implementation:
After analysing the given requirements, implement the required application:
with Object Oriented Programming style
following the rules of good programming style (e.g. adding comments, etc.)
using only the material covered in M251 (and its prerequisites)
Hints:
For each class, it is required to implement constructors, setters, getters, toString() method,
and any other necessary me -

We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you. So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in! Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did. If you are having problems getting started at all, then this may help: How to Write Code to Solve a Problem, A Beginner's Guide[^] Even if we did do your homework for you - which we don't - this would be very much the wrong place to post this!
