Java Interview Guide : 200+ Interview Questions and Answers - Set interfaces and implementations - HashSet, LinkedHashSe

The video tutorial covers the SET interface, emphasizing its unique characteristic of not allowing duplicate elements. It introduces the sorted set interface, which maintains elements in a sorted order, and the navigable set interface, which extends the sorted set with additional navigation methods. The tutorial also discusses implementations of the set interface, including hash set, linked hash set, and tree set, highlighting their differences in maintaining order and handling duplicates.
