* Understand the OO principles abstraction, encapsulation and inheritance
* Become familiar with the Java API
Setup
An individual repository for this lab has been created for you here (replace z5555555 with your own zID):
https://gitlab.cse.unsw.edu.au/z5555555/19T3-cs2511-lab02
Exercise
Modify the class StaffMember (inside package `staff`) so that it satisfies the following requirements:
* Attributes to store the staff member’s name, salary, hire date, and end date.
* Appropriate constructors, getters, setters, and other methods you think are necessary.
* Overridden `toString()` and `equals(..)` methods. Use what you learnt from the tutorial, but make sure you understand what these methods are doing.
* Javadoc for all non-overriding methods and constructors.
Create a sub-class of `StaffMember` called `Lecturer` in the same package with the following requirements:
* An attribute to store the school (e.g. CSE) that the lecturer belongs to
* An attribute that stores the academic status of the lecturer (e.g A for an Associate Lecturer, B for a Lecturer, and C for a Senior Lecturer)
* Appropriate getters and setters.
* An overriding `toString()` method that includes the school name and academic level.
* An overriding `equals(...)` method.
* Javadoc for all non-overriding methods and constructors.
Create a class `StaffTest` in the package in the package `staff.test` to test the above classes. It should contain:
* A method `printStaffDetails(...)` that takes a `StaffMember` as a parameter and invokes the `toString()` method on it to print the details of the staff.
* A `main(...)` method that:
* Creates a `StaffMember` with a name and salary of your choosing.
* Creates an instance of `Lecturer` with a name, salary, school and academic status of your choosing.
* Calls `printStaffDetails(...)` twice with each of the above as arguments.
* Tests the `equals(..)` method of the two classes. Use [the documentation](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Object.html#equals(java.lang.Object)) for `Object.equals(...)` as a guide for what you should test.
Submission

```
Prologue
With any leftover time in your lab, look at the specification for assignment 1 and try to come to a concrete understanding of the requirements. You may even try to write down an initial set of CRC cards.
