Topic: Software Architecture
Focus: Pattern Abuse
Java: Pattern Abuse
Answer
The Decorator Pattern adds behavior to objects dynamically.
Instead of altering a class, use Decorators to add responsibilities. In a Java e-commerce system, you could use decorators to add features like gift wrapping or express shipping to order processing, without modifying the original order class.
