Abstract Instructor Eccentricities Create a new package called Lab04B. All the code for this part should reside in there. In universities, various many factors determine how much instructors get stressed but the biggest factor is unread mail! In this part of the lab, we'll build a model of how Grad students, Lecturers, and Faculty cope with it, along with how it affects their eccentricities (funny behaviours) and respect. Instructor All three of these categories have an age, an int representing their unread mail, and a positive number representing the eccentricities. We should take advantage of these common aspects and abstract them into an abstract class called Instructor (in a file called Instructor.java). Create getters for the three variables, and a constructor for this class. The constructor should only accept settings for the unread mail and the instructor's age. Add an abstract method there called cope() that returns nothing. Anything that inherits from Instructor will need to implement this method. Add a method called stress() that returns an int. The stress is equal to the unread mail, and it's maximum value is 1000. Add a method called respect() that returns an int. Respect is equal to the instructors age minus the eccentricities (age - eccentricities). This value must be positive so if it's negative return 0. Add a method to reduce the amount of mail the Instructor has. Call it reduceMail(int readMail) and it should return nothing. Ensure that unread Mail doesn't become negative. Add a method to add to eccentricities. Call it addToEccentricities(int eccentricities) and it should return nothing. This method should prevent the eccentricities from becoming negative as well (but the parameter eccentricities can be negative). Notice here how our setters enforce an encapsulation for any Instructor subclasses. In other words, we have a single common location for how the properties get setup. Furthermore, we don't have to reimplement these checks in our subclasses. Lastly, let's implement a method for getting mail. It should be called getMail(int newMail). The method should add this new mail to the unreadMail. Then, 20% of the time (e.g. `Math.random() < 0.2`) either gain 2 eccentricities or lose 2 eccentricities randomly (50% chance for each). After this, if the Instructor finds that their stress is higher than their respect, they must cope with it. Grad, Lecturer, and Faculty Let's make use of our Instructor abstraction!
