A collection of elements, such as a linked list, is produced one element at a time by an object known as an iterator.
<h3 /><h3>What is an iterator?</h3>
Java's collection framework uses iterators to fetch elements one at a time. It is a universal iterator since any collection object can use it. We can do both read and remove actions with the help of an iterator. It is an enhanced version of enumeration that now can remove an element. Every time we want to enumerate elements in any collection framework defined interfaces, such as Set, List, Queue, Deque, and any implemented classes of Map interface, we must use an iterator. The only cursor offered across the board by the collection framework is the iterator. Calling the iterator() function on the collection interface will provide an iterator object.
