The objective of the lab is to take the UML Class diagram and enhance last week's Employee class by making the following changes:
1. Create a class called Salaried that is derived from Employee.
2. Create a class called Hourly that is also derived from Employee.
3. Since all classes/objects inherit from java.lang.object class, change the "displayClass" information method to override the java.lang.object "toString" method.
4. Override necessary method(s) in each of the new subclasses as applicable.
