Make Employee abstract
Attributes (data members)
• name, id
Behaviors (methods)
• constructors
• get, set, toString
• abstract method --> work

Individual Employees extend Employee
• constructors use super
• override the work method
• override the toString method, but use
• super (see p. 398) output name and job
• create a few extra methods in extended classes
• e.g. Administrator has a department, get and set it
• Nurse has a number of patients
• main should have objects of each class as well as
• array of Employee(s)
