Examples of HashSet Using Iterator

The video tutorial explains how to iterate through a hash set in Java using the Iterator interface. It covers the basics of creating an Iterator object, using the next() method to traverse elements, and employing a while loop with the hasNext() method for efficient iteration. The tutorial also highlights key differences between List and Set collections, emphasizing that Lists allow duplicates and maintain order, while Sets do not. This knowledge is particularly useful in automation testing scenarios like Selenium.
