Iterators allow the caller to remove elements from the underlying collection during the iteration with well defined semantics. method names have been improved. this interface is a member of the java collections framework. Java iterator interface of java collections allows us to access elements of the collection and is used to iterate over the elements in the collection ( map, list or set ). it helps to easily retrieve the elements of a collection and perform operations on each element. iterator is a universal iterator as it can be applied to any collection object. Java iterator is an interface that is practiced in order to iterate over a collection of java object components entirety one by one. it is free to use in the java programming language since the java 1.2 collection framework. it belongs to java.util package. though java iterator was introduced in java 1.2, however, it is still not the oldest. Iterator takes the place of enumeration in the java collections framework. iterators differ from enumerations in two ways: iterators allow the caller to remove elements from the underlying collection during the iteration with well defined semantics. method names have been improved. this interface is a member of the java collections framework.

Then the necessary custom class ‘listiterator’ is created, which will implement the iterator interface, along with it the functionalities of hasnext () and next () are also to be implemented. these two functions form the core of iterable and iterator interface. import java.util.iterator; class list<t> implements iterable<t> {. There are three iterators in java. 1. enumeration. it is an interface used to get elements of legacy collections (vector, hashtable). enumeration is the first iterator present from jdk 1.0, rests are included in jdk 1.2 with more functionality. enumerations are also used to specify the input streams to a sequenceinputstream. Public interface characteriterator extends cloneable. this interface defines a protocol for bidirectional iteration over text. the iterator iterates over a bounded sequence of characters. characters are indexed with values beginning with the value returned by getbeginindex () and continuing through the value returned by getendindex () 1.
