What is an Iterator class?

[chinmay]

A class that is used to traverse through the objects maintained by a container class. There are five categories of iterators:
random access.
input iterators
forward iterators
output iterators,
bidirectional iterators.
An iterator is an entity that gives access to the contents of a container object without violating encapsulation constraints.

In computer programming, an iterator is an object that enables a programmer to traverse a container, particularly lists. Various types of iterators are often provided via a container's interface.

Thank you~!

Iterator is a design pattern. It specifies how to navigate through the elements of a collection. Collection is a collection like array, stack, list.

Java iterator is an interface belongs to collection framework allow us to traverse the collection and access the data element of collection without bothering the user about specific implementation of that collection it.

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.

An iterator is an object that represents a stream of data. An iterator is a generalisation of a pointer, used for abstracting addresses of elements of different structures.

Iterator is an interface and a object which enables a developer to traverse a container, particularly lists. Iterators are used in Collection framework in Java to retrieve elements one by one.
