Symbol Tables & Binary Search Trees – Efficient Data Access in Java
In this tutorial, we explore the powerful concept of symbol tables—also known as associative arrays, maps, or dictionaries—and how they enable efficient data access and retrieval. We define a clean API and implement two foundational approaches: binary search on sorted arrays and sequential search on unordered lists.
When keys are Comparable, we extend the API to support advanced operations like min, max, floor, ceiling, rank, and select. To optimize performance, we introduce the binary search tree (BST) data structure and analyze its behavior.
