[](https://classroom.github.com/a/3WioXqLZ) :sectnums: :nofooter: :toc: left :icons: font :data-uri: :source-highlighter: highlightjs :stem: latexmath = Inh.01 -- Employees You are going to represent the various employees of a company: * Workers * Office employees ** Some are managers IMPORTANT: This is a rather short assignment -- you are expected to read & understand the code carefully and reflect on how good your understanding of inheritance already is == Class Descriptions === `Employee` All employees have _common_ properties: * Name ** Requirements: *** At least two characters *** First character is a letter (not a digit) _and_ is uppercase ** If invalid set to 'ERROR' * Gender * Department * Salary * Can represent themselves as a `string` But nobody is _just_ an employee => everyone is either a `Worker`, `OfficeEmployee` or `Manager`, so there are _no_ instances of `Employee`. ==== String Representation * Contains the name and the department the employee works at * If gender is either male or female this information is added, but omitted for those employees who identify as divers * Examples: ** `My name is Mia, I identify as female and I work at the department Accounting` ** `My name is Steph and I work at the department Marketing` === `Worker` A worker is an employee which performs physical labor. * They work a certain amount of hours each month ** This value cannot exceed 16 hours for 31 days a month and can also not be negative *** Try to use https://learn.microsoft.com/en-us/dotnet/api/system.math.clamp?view=net-7.0[Math.Clamp] here ** You may ignore that months are usually shorter and that people have free weekends * They get paid a certain amount per hour ** Which cannot be negative either * Their salary is calculated by multiplying the hours worked by the wage per hour * The string representation is extended by adding 'as a worker' ** Example: `My name is Max, I identify as male and I work at the department Welding as a worker` ** Do _not_ duplicate the basic part! TIP: One constructor calls the `base` constructor, but the other one calls another _class_ constructor -- make sure you understand the difference and how the `base` constructor will eventually be called in both cases === `OfficeEmployee` Some employees work at an office. * An office clerk has a fixed salary per month ** Which cannot be negative * The string representation is extended by adding 'as an employee' ==== `Manager` A manager is the head of a department. * Managers also work at an office * They have a fixed salary per month, just like regular office employees, but that is increased by 20% to determine their actual salary ** Try to implement this using `base.Salary` * The string representation is _changed_: ** Does not include gender information ** Example: `My name is Anna and I'm head of the Sales department` == Tasks * Try to create the class diagram _before_ looking at the provided starter code ** You need to learn how to turn a pure, textual description of a scenario into a class diagram and then into code => making it easier for yourself by cheating now will make it harder later on * It is perfectly fine to _revise_ your diagram once you looked at the code and realized you had chosen an incorrect visibility modifier or data type,... ** You'll learn quite a lot about how to make these decisions by actively comparing my choices with the ones you made and trying to figure out how we reached different (or similar) conclusions === Class Diagram * Your first task is to create a UML _class diagram_ for this application. * Use https://plantuml.com/class-diagram[PlantUML] for this job * Make sure to use the correct _visibility_ modifiers * Include all _relationships_ ** e.g. 'is a',... === Implementation * Business as usual: ** Implement the application ** Unit Tests have been provided * Take a detailed look at the provided XMLDoc: what could `<inheritdoc cref="..." />` mean and why do we suddenly need this tag now? ** Internet search is allowed 😉 NOTE: Make sure to carefully check which classes are `abstract` or `sealed` and how the inheritance structure is represented in code -- you'll have to do that by yourself soon ==== Sample Run Take a look at `Program.cs`: _why_ do we get different outputs despite operating on a `List<Employee>` which only contains objects of type `Employee`? image::pics/sample_run.png[Sample Run]
