Person-employee : Out of context
Posted by Herman Jansen on 03 Nov 1998, 3:23 AM
You really sould not discuss inheritance vs. composition but you
should discuss inheritance vs. composition-interfaces. Any other
way makes the discussion incomplete.
For all of you who want to read a very good text on inheritance
vs. composition-interfaces, specially on the person-employee
issue, please read the book : 'Java Design : Building better Apps
& Applets' by Peter Coad. There is a complete chapter on
inheritance vs. compositon-interfaces. For the person-employee issue : An employee is not a special kind
of person, it is a normal person like you and me.
Employee is just a role you play in life as a person.
Therefor do not use inheritance.
