Java Programming for Complete Beginners - Java 16 - Step 15 - Understanding Data Structures - Array, LinkedList, and Has

The video tutorial covers basic data structures, focusing on arrays, linked lists, and hash tables. Arrays store elements sequentially, making retrieval easy but deletion costly. Linked lists allow easier insertion and deletion but require traversal for retrieval. Hash tables combine array and linked list advantages, using a hashing function to store elements in buckets, enabling fast searches and efficient operations. The tutorial also explains implementing hashing functions in Java using hash codes.
