What is a Java virtual machine?Java virtual machines, literally, are like some kind of machine, but the Java virtual

, creation, and destruction times. According to the Java Virtual Machine Specification (second edition) (hereinafter referred to as VM spec), the JVM includes the following runtime data regions:1. Procedure counter (program Counter Register):Each Java thread has a program counter to hold which instruction executes to t

Java run-time memory areaWhen running a Java program, a Java Virtual machine divides the area of memory it manages into several different regions. Each zone has its own purpose, creation, and time to destroy. Some exist with the startup of the

I. Introduction of the JVMThe Java language is cross-platform and compatible with various operating systems. The cornerstone of implementing cross-platform is virtual machine (JVM), virtual machine is not cross-platform, so different OS need to install different JDK version
