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.

What are the main differences between an array and a linked list?

Explain how insertion and deletion operations work in a linked list.

Describe the concept of a hash table and its advantages.

How does a hashing function determine the bucket for storing an element?

What happens when you try to insert an element into a bucket that already contains elements?

Discuss the efficiency of hash tables compared to arrays and linked lists.

What role does the hash code method play in implementing a hashing function in Java?
