Java Iterator & Iterable Interfaces Explained | Java Mastery Series
Master the Java Iterator! In this tutorial, we dive deep into the safest and most effective ways to traverse data inside the Java Collections Framework using the Iterator and Iterable interfaces.
We start by looking at the core Iterator interface to understand why it is fundamentally better and safer than a standard for loop (especially when removing elements). Next, we upgrade to the ListIterator to learn how to traverse lists in both directions. Finally, we explore the root Iterable interface that makes the enhanced for-loop possible, and look at how to use the modern forEachRemaining method introduced in Java 8 to write incredibly clean, functional code.
Whether you are a beginner or prepping for a Java backend interview, this video covers everything you need to know about navigating Java Collections!
