Building a Hash Table from Scratch
Understand how to implement a hash table in Java by using the bucket strategy to handle collisions. Learn to create hash entries with key/value pairs and use a hash function to map keys to array positions. This lesson helps you build foundational knowledge for coding interviews involving hash tables.

Hash Table using Buckets
As said earlier, Hash Tables are implemented using Arrays. The implementation of a Hash Table is quite simple. In this lesson, we will use Bucket strategy to avoid collisions. In the Bucket strategy, we chain different arrays together to store elements, where each array is called Bucket.
The size of the Hash Table is set as:
