In the previous chapters, we have covered creational patterns, object-oriented programming patterns that help us with object creation procedures. The next category of patterns we want to present is structural design patterns.

A structural design pattern proposes a way of composing objects for creating new functionality. The first of these patterns we will cover is the adapter pattern.
