* items once only, in sequence, by successive calls to the next method. It is
* also possible to remove elements from the underlying collection by using the
* optional remove method. Iterator is intended as a replacement for the
* Enumeration interface of previous versions of Java, which did not have the
* remove method and had less conveniently named methods.
