What is Iterator? | Java Iterator Explained: Traversing Collections in Java

Welcome to our Java Collection Framework series! In this video, we dive into the concept of iterators and how they are used in Java collections.

**What is an Iterator?**
An iterator is an interface in Java that provides a way to access elements of a collection one at a time without exposing its underlying structure. It allows you to traverse through the elements of a collection sequentially.

**Key Topics Covered:**
- Introduction to the Iterator interface in Java
- How iterators are used to traverse different types of collections (e.g., ArrayList, LinkedList, HashSet)
- Iterator methods: hasNext(), next(), remove()
- Benefits of using iterators for collection traversal
- Iterators vs. traditional for-each loops: when to use each approach

**Why Learn About Iterators?**
Understanding iterators is fundamental to effectively working with Java collections. It enables you to iterate over elements in a collection in a controlled and efficient manner, providing flexibility and encapsulation.

**In This Video:**
Join us as we explore the Iterator interface in Java, demonstrating how it simplifies the process of iterating through collections and discussing best practices for using iterators in your Java projects.
