Respond to an unknown method call: Difference between revisions
Languages like C++ and Java also have a dynamic dispatch mechanism; it's just statically enforced that there *is* a method, *which* one is called is selected at runtime

Line 2:
Demonstrate how to make the object respond (sensibly/usefully) to an invocation of a method on it that it does not support through its class definitions. Note that this is not the same as just invoking a defined method whose name is given dynamically; the method named at the point of invocation must not be defined.
This task is intended only for object systems that use a dynamic dispatch mechanism without static checking.
