Java was designed with the principle of &#8220;write once, run anywhere,&#8221; and its approach to data types reflects this goal. Unlike languages where data type behavior can vary by platform, Java enforces strict rules around how data is stored and manipulated. This document provides a clear and comprehensive overview of Java\u2019s primitive data types, their fixed sizes, and the reasoning behind certain design choices\u2014like why Java avoids unsigned integers.
