Introduction

The Strategy and Bridge patterns provide solutions to apply polymorphism in more flexible way than you can accomplish with only inheritance.

The patterns are almost identical, differing mostly in intent only. Though it is this difference that create implementation variations targeting the respective problems.

Problem

Strategy
How to use different algorithms in a flexible, polymorphic way.

Bridge
How to structurally abstract a varying concept and it's implementations, in a way that doesn't break encapsulation.

Interesting example, tho IMO overkill for an 'emailer' class. Explains the concept well though.
