| + | The difference between strategy and state is the intent. The [[Strategy|Strategy pattern]] is used when the purpose is to provide different functionality, using different algorithms. The [[State|State Pattern]] is used when the propose is to represent the different internal states that the object can have. Doing this using the state pattern has some advantages such as explicitly defining valid stated and preventing the object from entering a possibly invalid state. Strategy provides functionality. State stores information. Does that help? -[[User:Jason Clutterbuck|Jason Clutterbuck]] 23:07, 11 September 2008 (UTC) | ||
