State

Allow an object to alter its behavior when its internal state changes. The object will appear to change its class.

Chain of Responsibility

Avoid coupling the sender of a request to its receiver by giving more than one object a chance to handle the request. Chain the receiving objects and pass the request along the chain until an object handles it.

-Ajay

Command

Encapsulate a request as an object, thereby letting you parameterize clients with different requests, queue or log requests, and support undoable operations.

-Gaurav

Interpreter

Given a language, define a represention for its grammar along with an interpreter that uses the representation to interpret sentences in the language.

-Duggal

Iterator

Provide a way to access the elements of an aggregate object sequentially without exposing its underlying representation.

-Ajay

Mediator

Define an object that encapsulates how a set of objects interact. Mediator promotes loose coupling by keeping objects from referring to each other explicitly, and it lets you vary their interaction independently.

-Harsha

Memento

Without violating encapsulation, capture and externalize an object's internal state so that the object can be restored to this state later.
