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 a kind of polymorphism. In Java/C#/C++, there is polymorphism through inheritance and overriding, but that is not multiple dispatch, which is based on two or more arguments (not just this, like in Java/C#/C++)
