Understanding HashMap Internals: Table Initialization, Resizing, and Load Factor

This article explains the inner workings of Java's HashMap, covering its array‑plus‑linked‑list (or red‑black tree) structure, lazy table initialization, default capacity and threshold, resizing mechanics, the rationale behind power‑of‑two table lengths, index calculation using bitwise AND, and the significance of the 0.75 load factor.
