Iterator Pattern

submited by krishnas on Sat Oct 16th, 2010

Because of the excellent job of the Java development team at Sun (now Oracle), Java developers are probably more familiar with the Iterator design pattern than developers in other languages. So much so that we seldom refer to traversing over a collection, but instead use the vernacular of “iterating over” a collection. While you may have used iterators built into the Java programming language, this article shows you the rational behind iterators and describes how to build an iterator of your own.
