Class Diagram
Object and Class adapter
Above class diagram is for object adapter, below is class adapter.
- Object uses composition, class uses subclassing.
Let's take a example of Enumeration and Iterator. Task is to Adapt an Enumeration to an Iterator.

Home Work - Adapt an Iterator to Enumerator
Decorator - Doesn't alter the interface, but adds responsibility.
Adapter - Converts one interface to another.
Facade - Makes an interface simpler.
