Java Virtual Machine Specification

The Java Virtual Machine (JVM) Specification defines how the JVM should function, serving as a blueprint for implementing the environment that executes Java programs. It specifies the behavior, rules, and features needed to run Java bytecode—an intermediate code generated from Java source code—consistently across different systems. This ensures portability, allowing the same Java program to run reliably wherever a compatible JVM is available. Think of the JVM as an engine that interprets and executes Java instructions, following a detailed guide to maintain uniformity and efficiency across various platforms.
