The main article is read the deep understanding of Java Virtual Machine: JVM advanced Features and Best Practices Chapter II: Java memory area and memory overflow exceptionSome of the notes and summaries.Okay, here we go. If there are any errors or omissions, please point out.I. OverviewFirst, a picture.This diagram ma

multithreading on multithreaded platforms should provide a solution to the Problem.The JVM is a virtual computer, it will also face multi-threaded concurrency problems, Java programs run on the Java Virtual machine platform, Java programmers can not directly control the underlying thread to register cache memory synch

OverviewThere is a high wall between Java and C + + that is surrounded by dynamic memory allocations and garbage collection techniques, and people outside the walls want to go in, but the people inside the wall want to come out.For developers engaged in C, C + + program development, in the field of memory management, they are the highest power of the emperor is t

the JVM. When we create objects, they are stored in the Java heap memory. To facilitate garbage collection, the Java heap space is divided into three zones, called New Generation, old Generation or tenured Generation, and perm space. You can resize the Java heap space by using the Jvm's command-line Opt

Java Memory Model-basic, java Memory ModelClassification of basic concurrent programming models In concurrent programming, we need to deal with two key issues: how to communicate between threads and how to synchronize between threads (here the thread refers to the active entity of concurrent execution ). Communication

1. Run-time data areaThe 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 time of creation and destruction: Some regions exist with the start of a virtual machine process Some regions are built and destroyed depending on the s

What we often do is divide the Java memory area into two simple types: heap memory and Stack memory. This division is more coarse grained, and this division is focused on the two types of memory domains that we are most concerned about, which are closely related to object

Java memory overflow and java memory overflowMemory Area During Java program execution, the Java Virtual Machine divides the memory it manages into several different data regions. The

In the previous articles, the system learned the next JVM memory structure, Java memory model, Java object model, but found themselves or the three concepts and differences are more vague, silly points unclear. So there is this article, this article is mainly on these three technical points to make a summary and distin

statements in the Code and the fault code such as the result set is not closed or code redundancy. The second step is to detect Java Memory leakage. Here we usually use some tools to check the memory leakage of Java programs. There are already several professional Java

Java as an object-oriented, cross-platform language, its object, memory, etc. has been a difficult point of knowledge. And many of the concepts of the name look so similar, many people will be silly to divide the unclear. For example, the JVM memory structure, the Java memory
