Along with above benefits names of methods defined in Iterator are also very convenient which is not major difference but make use of iterator more easy. Iterator Important Points Iterators are of two types Fail-Fast and Fail-safe, Use Fail-fast when no modifications are needed, else use Fail...

other collection. Same approach is followed by collection classes also and all of them have inner class implementation of Iterator interface. Let’s write a simple iterator pattern test program to use our collection and iterator to traverse through the collection of channels.IteratorPatternTest.java...
