Topics Covered in This Video:

1.Set Interface:
Define the Set interface and its importance in collections that do not allow duplicate elements.
Highlight key features and scenarios where sets are ideal.

2.HashSet:
Explore the characteristics of HashSet for storing unique elements.
Discuss its hash-based structure and efficient performance for add, remove, and contains operations.

3.LinkedHashSet:
Introduce LinkedHashSet, emphasizing its ability to maintain insertion order.
Compare it with HashSet and highlight its use cases.

4.TreeSet:
Explain the TreeSet class for sorted collections.
Discuss its use of a red-black tree structure and how it maintains a natural or custom ordering.

5.HashMap:
Define HashMap and its key-value pair storage mechanism.
Highlight its unsynchronized nature and use in scenarios requiring fast lookups.

6.LinkedHashMap:
Discuss LinkedHashMap for maintaining insertion or access order.
Explore its advantages over HashMap in specific use cases.

7.TreeMap:
Explain TreeMap as a sorted map implementation using a red-black tree.
Discuss its applications in scenarios where sorted key-value pairs are required.

8.Collections Class:
Introduce the utility methods provided by the java.util.Collections class.
Discuss common operations like sorting, shuffling, and thread-safe wrappers for collections.

9.Hashing Mechanism:
Explain the concept of hashing and its role in efficient data retrieval.
Discuss how hashing works in HashSet and HashMap and the importance of hash codes and collisions.
