Scenario Two

Read the scenario below and answer the questions that follow:

You are developing an application to manage staff member details for an organization. Each staff member's data includes their name, birthdate, and appointment type $($which can be one of the following: permanent, part$-$time, or contract$).$ The appointment type should be stored and handled as an enum. The application will feature a GUI that allows users to input staff details. Once entered, these details should be stored in a list or other appropriate container $($box or cylinder$).$ Additionally, the user should be able to save this list to a file in a human$-$readable format when needed.

As you design this solution, ensure that you adhere to basic design principles, avoid common antipatterns, and implement all necessary getter and setter functions.

$2\mathrm{.}1.$ Write a piece of code which define a class to represent a staff member in this application $(10)$

$2\mathrm{.}3.$ How would you handle storing a list of staff members in this application?

$2\mathrm{.}4.$ What basic design principle should be followed when designing the StaffMember class?

$2\mathrm{.}5.$ Write a code that define a method to save the staff members list to a file in a human$-$readable format?

$2\mathrm{.}6.$ Design and implement the StaffManager class that will manage the list of staff members. Include methods for adding new staff members, removing staff members, and retrieving all staff members.
