Implementing Set Interface

The video tutorial explains the Set interface in Java, focusing on HashSet, TreeSet, and LinkedHashSet. It highlights the key differences between Set and List interfaces, particularly the non-acceptance of duplicate values in Set. The tutorial provides examples to illustrate when to use Set or List, such as in e-commerce scenarios. It also discusses the lack of guaranteed order in Set elements compared to ArrayList. A demonstration of HashSet is provided, showcasing its methods like add, remove, and checking for duplicates. The tutorial concludes with a brief mention of the Iterator interface, which will be covered in the next lecture.
