There are several design patterns allow us to hide the type of an object even from those who seek to create it. These patterns are known as Factories.

One of the great benefits of object-oriented programming is polymorphism. Perhaps no pattern illustrates this better than the Strategy pattern.

To break the dependency of a client upon a server when you can't modify the server, the Adapter pattern is an alternate approach to last month's Abstract Server pattern. The class and object versions of this pattern are offered and the article ends with an anonymous inner class implementation.

The Abstract Server pattern is one of the simplest of the object-oriented design patterns. We use it when we want to break the dependency of a client upon a server, for the purpose of protecting the client from changes to the server, and to preserve the ability to extend the client to use other servers.
