The development of a game playing framework using interface-based programming

An interface can be defined as a contract that outlines the terms of usefor a class of objects. When a class implements an interface, the classis agreeing to the contract outlined by the interface. In other words,the class is agreeing to provide the logic for all the methods listed inthe interface. The single most important attribute of an interface isits implementation independence. The contract enforced by an interfacedoes not make any assumptions about how the methods are implemented; theimplementation strategy is left to the implementing class. By enforcingwhat a class of objects must do, without placing restrictions onhow it is done, interfaces play a key role in making thebehavior of objects more flexible.
