The Iterator interface in Java is a part of the Java Collections Framework and is used to iterate over the elements of a collection. It provides methods to traverse the collection and optionally remove elements from the collection.
This guide covers various methods available in the Iterator interface. Each method is described in simple terms to help beginners understand how to use them. These methods allow you to check for more elements, retrieve the next element, and remove elements during iteration.
For more detailed information, please refer to the official Java SE Documentation.
