Iterators in C++ (stl) vs Java, is there a conceptual difference?

Question

I\'m returning to c++ after being away for a bit and trying to dust off the old melon.

In Java Iterator is an interface to a container having methods: hasNext

Answer 1

C++ iterators are a generalization of the pointer concept; they make it applicable to a wider range of situations. It means that they can be used to do such things as define arbitrary ranges.

Java iterators are relatively dumb enumerators (though not so bad as C#'s; at least Java has ListIterator and can be used to mutate the collection).
