#3 Decorator Pattern

When to Use Decorator Pattern?

Add New Responsibility(functionality) to the class,without breaking the existing functionality.

Usage:

1.Component as abstract class/Interface.

2.Concrete Components Implementing the Components.

3.Decorator as abstract class/Interface with Component as member initialized via constructor.

4.Concrete Decorator Implements Decorator.

Consequence:
Functionality are added at runtime,Hard to debug(Since object implements both Concrete Component and Concrete Decorator).
