Overview:
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 method
3
If the user tries to do an operation that could violate the state of objects, the operation
should be ignored and the application should display an error message (e.g. adding a citizen
twice to the list, etc.)
Checking equality of any 2 objects should be done via the equals() method
There is a class that will do the main job of the application as follows:
o It has one collection to store the whole data (all citizens)
o It has static methods, one for each operation happens frequently
o When you add a citizen to the list, a message shou -
