Java Iterator is an interface that provides methods for iterating over elements in a collection, such as Java Lists, Java Sets, and Java Queues. It provides methods like Java hasNext() and Java next() to traverse through the elements, and Java remove() to delete elements during iteration. Introduced in Java 1995 with Java 1.0, Iterator is a fundamental part of the Java Collections Framework and is widely used for looping through collections in a safe and flexible manner.
