Adapter (Adapter mode)

Adapter mode:

Transforms the interface of one class into another interface that the customer wants. The adapter mode makes it possible for those classes that would otherwise not work together because of incompatible interfaces to work together.

There are two types of adapter modes:

1) class adapter (by inheritance)

2) object Adapter (Takes object combination mode)
