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

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

loaded with the launcher loader, but the purpose of Jdni is to centrally manage and find resources, It needs to invoke the code of the Jdni interface provider implemented by other independent vendors and deployed under the classpath of the application, but the startup class does not recognize the code. To solve these problems, the Java design team provides an elegant design: the thread context ClassLoader.

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

Run-time data regionThe Java Virtual machine divides the memory it manages into several different data regions during the execution of a Java program. These areas have their own uses, as well as the creation and destruction of time, and some areas exist as the virtual

1 Java technology and Java Virtual Machine Speaking of Java, people first think of Java programming language. However, Java is actually a technology, which consists of four aspects:

aging into the old age. The following simple example shows the relationship between the Java Heap,theJava method area, and the Java stack. The code is as follows:Package Cn.xhgg.test;public class Heaptest {private int id;public heaptest (int id) {this.id = ID;} public void Show () {SYSTEM.OUT.PRINTLN ("ID: " +id);} public static void Main (string[] args) {heaptest H1 = new heaptest (1); Heaptest h2 = new
