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.

What is the underlying data structure used in a hash map?

What is the main difference between a hash map and a hash table?

Can a hash map store a key with a null value? Explain.

What characteristic does a linked hash map maintain?

What additional interface does a tree map implement?
