What's the difference between Polymorphism and Multiple Dispatch?

Question

...or are they the same thing? I notice that each has its own Wikipedia entry: Polymorphism, Multiple Dispatch, but I\'m having trouble seeing how the concepts differ.

Answer 1

Multiple Dispatch is more akin to function overloading (as seen in Java/C++), except the function invoked depends on the run-time type of the arguments, not their static type.
