JAVA PLEASE. SUPER SIMPLE!!! Looks like a lot but it is a small task!!! Below is a program that is already completed and runs perfect. The task is to move the employee information from the Test Class to the Employee Class or the Faculty class (which is a subclass of employee). Basically these lines(which are in the Test Class) need to be moved to the Employee or Faculty Class. The Test class will then need to be altererd so that the output remains the same! So in short, Move all lines in BOLD, to the Employee Class or Faculty Class, and rewrite some of the TEST CLASS so that it still outputs the information as it did before.
