Table of Contents
Chapter 8.  Interfaces

Sometimes there is some confusion about when to use interfaces and when to simply create abstract methods and place them in a super class. Here are a few guidelines:

  • Use an abstract base class method when the functionality is tightly coupled with the object itself

  • Use an interface when the functionality is auxiliary to the object

  • Use an interface when the functionality can be applied globally to other unrelated objects
