本文转自： http://www.alvestrand.no/objectid/ What is an object identifier?object identifiers are, basically, strings of numbers.

objects are key to understanding object-oriented technology. Look around right now and you'll find many examples of real-world objects: your dog, your desk, your television set, your bicycle.
