Java Programming for Complete Beginners - Java 16 - Step 17 - Set Interface - Hands on - HashSet, LinkedHashSet and Tree

The video tutorial covers three types of sets in Java: HashSet, LinkedHashSet, and TreeSet. It explains how HashSet stores elements without any order, LinkedHashSet maintains the insertion order, and TreeSet keeps elements sorted. The tutorial includes examples of adding and printing elements in each set type, highlighting their unique properties. An exercise is provided to find unique characters in a list using these sets, emphasizing the choice of collection based on the desired order of elements.
