Överview: 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: . 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. : 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 anu other nece method
![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 should be displayed to the user to explain
the status of the operation (i.e. if it was successful or not)
Testing:
After implementing the required classes, design and implement a testing class to test them as
follows:
• Add at least 7 citizens to the collection that stores the whole data
• Add 1, 2 and 3 doses to different citizens and keep some citizens unvaccinated
Try to violate the state of the objects and show that your code prevents all violations.
• Show that the other operations that happen frequently are working fine
At the end, the whole data should be saved into a text file and this file should be saved
automatically inside the folder contains your Java project](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F530d1caf-ba78-4a55-8756-45d4c1001242%2F73c2644f-61c1-4cc8-98a2-42d186f62903%2Fwjwg8ha_processed.png&w=3840&q=75)

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
