.NET and Java J2ee design pattern interview question :-What is the difference between Object and class adapters?


Answer:

Below are the main difference between these 2 patterns.

Object adapter

Can adapt classes as well as sub classes since uses composition

More flexible since dynamic polymorphism can be used with composition

Class adapter

Can adapt classes or sub classes not both. As a result no need to re
implement the entire adaptee

More efficient since class adapter acts as adapter and adaptee
