Bridge Design Pattern

The Bridge pattern is designed to separate a class's interface from its implementation so you can vary or replace the implementation without changing the client code (see the Bridge pattern Wikipedia entry).

Lets see what that means in a simpler way.

In following example polymorphism is used inorder to give Person Class different implementations.

There are lot of people by same name. Say we want to introduce a new property home town.
If we follow this pattern code would be as follows.

That is code is hard to maintain and reusability is low. We can use Bridge design pattern to improve that code by seperating implementation of home town.
