Selenium WebDriver with Java - Basics to Advanced and Frameworks - Examples of HashSet Using Iterator

The video tutorial explains how to use the Iterator interface to traverse elements in a HashSet in Java. It covers the basics of creating an Iterator object, using the 'next' method to access elements, and employing a while loop with 'hasNext' to iterate through all elements. The tutorial also highlights the differences between List and Set collections, emphasizing that Lists allow duplicates and maintain order, while Sets do not. Practical examples and common interview questions related to Iterator usage are discussed.

How would you print the value at the 97th index using an Iterator?
