extend: When you derive a class from a base class we say the derived subclass extends the base class. An interface can also extend another interface. In contrast, when a class provides the methods (possibly abstract) necessary to conform to some interface we say that class implements the interface. Extending a class is closely related to implementing an interface. A new class can extend at most one superclass, but it may implement several interfaces.
