Java Programming for Complete Beginners - Java 16 - Step 23 - Map Interface - Implementations - HashMap, HashTable, Link

The video tutorial explores various map implementations, including hash map, hash table, linked hash map, and tree map. It highlights the differences between hash map and hash table, such as synchronization and thread safety. Linked hash map maintains insertion order but is not sorted, while tree map stores data in a sorted order and implements a navigable map interface. The tutorial concludes with a summary of these implementations.
