NonExempt means the employee is paid by the hour and receives 1.5 times the hourly rate for hours worked over 40. Each Employee has an id number which is a string. They also have a name. Employee should be an abstract class with the member variables described in number 2. Employee should have an abstract method called findPay, a toString method, and it should implement the Comparable interface.
