A class has responsibilities that define the purpose,

virtue of the semantics of the class. To satisfy its
responsibilities, a class offers various services as
determined by a contract. Services are functions or means
through which a class satisfies its obligations. A contract
is an agreement between a class and other classes. An
operation specifies or provides a declarative description
(interface/what) of a service/contract or one construct
thereof; that is, an interface declares (specifies) a
contract. A method realizes or provides a definition
(implementation/how) of a service/contract or one construct
