Java Iterator interface

An iterator is an interface that is used in place of Enumerations in the Java Collection Framework. Moreover, an iterator differs from the enumerations in two ways:

  1. Iterator permits the caller to remove the given elements from the specified collection during the iteration of the elements.
  2. Method names have been enhanced.

Iterator interface is a member connected with Java Collections Framework.
