Then why did you claim that a decent OO should never have a switch statement then? You argued that a decent language OO should never have a switch statement because polymorphic dispatch is the right way to handle it in OO languages, which implies that polymorphism can and should take the place of any switch statement. > What if, instead of reading strings from a file, Why don't you answer my question first, then I'll entertain whatever point you are trying to make with this example?
