Java Virtual Machine-Linux general technology-Linux programming and kernel information. The following is a detailed description. 1. What is a Java Virtual Machine? A Java

In this article we will explain the roles of each region and region in a Java virtual machine.One. Program counterWhat is a program counter and what is the function?Program technology is a small area of memory, mainly as a thread in the execution of the byte code indicator, the bytecode interpreter works by changing the value of this counter to select the next execution of the bytecode command, branch, loop

This blog will provide a conceptual explanation of the various areas of Java Virtual Machine memory, the role of these areas, the service objects, and the problems that may arise, which is what we are prepared to do later on to learn about Java memory management. Java

Java Virtual machine in the process of executing a Java program, it manages the memory divided into a number of different data regions, some regions with the virtual machine process started, and some areas are dependent on the use

The Java Virtual machine memory is divided into the following areas:1. Method Area: The method area is an area of memory shared by each thread that stores data such as class information, constants, static variables, and code compiled by the immediate compiler that have been loaded by the 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

Demonstrate the memory overflow scenario for each part of a Java virtual machine with a simple, small example program:(1). java Heap Overflow:The Java heap is used to store instance objects, as long as the objects are constantly created, and the GC roots is guaranteed to hav

Preface　　If someone asks you what the memory area of Java is divided into, many people might say: heap, stack, method area .... I personally understand that Java can relate to the "memory Area" from the developer's point of view in two ways: First, the Java Virtual Runtime data area, and the second,

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
