Chapter Arrangement Memory Management Overview Garbage Collection Mechanism Performance problems Processing of unmanaged resources in C # Highlights References Memory Management Overview Memory Management is a very important part of any programming language, but it is a pity that no programming language is perfect for memory management, each language focuses on both performance efficiency and syntax and semantics usability. For example, C ++,

An important feature of the Java language is the introduction of an automatic memory management mechanism, so that developers do not have to manage the memory in the application on their own. C/C ++ developers need to use functions such as malloc/free and new/Delete to explicitly allocate and release memory. This puts forward high requirements for developers, which may cause problems such as memory access errors and Memory leakage. A common problem is that "dangling references" occurs, that is,

methods zone also known as permanent generation (Permanent Generation) The method area is shared by all threads, and the zone holds all the fields and method bytecode, as well as some special methods such as constructors, where the interface code is defined.The method area contains the structure information for each class, including constant pools, field descriptions, method descriptions, and so on.The restrictions on this area in the VM Space description are very loose, with the exception

Reasons for the garbage collection mechanism In java, when no object reference points to the memory originally allocated to an object, the memory becomes garbage.

1. Core Idea of the garbage collection AlgorithmThe Java language sets up a garbage collection mechanism to track the objects in use and discover and recycle objects that are no longer used (referenced. This mechanism can effectively prevent two risks that may occur in dynamic memory allocation: Memory depletion caused by excessive memory spam and illegal Memory Reference caused by improper memory release.T

Why to divideThe generational garbage collection strategy is based on the fact that the life cycle of different objects is not the same . Therefore, different life cycle objects can be collected in different ways to improve the efficiency of recycling.In the course of running a Java program, a large number of objects are generated, some of which are related to business information, such as session objects, threads, and socket connections in HTTP reque

JVM memory management, garbage collection, and jvm Memory Management I. JVM Memory Structure The Java Virtual Machine divides the memory into several different management zones. These regions have their own purposes. Based on their characteristics, they undertake different tasks and use different algorithms for garbage collection. It consists of the following parts: Program Counter Register, JVM Virtual Mac

The Java language may be the most widely used programming language that relies on garbage collection, but it is not the first. Garbage collection has become an integral part of many programming languages, including Lisp, Smalltalk, Eiffel, Haskell, ML, scheme, and Modula-3, and has been in use since the early the 1960s. In this article in Java theory and Practice, Brian Goetz describes the most commonly use

The above program creates many chair objects, and at some point after the garbage collector starts running, the program stops creating the chair. Because the garbage collector may run at any time, we don't know exactly when it starts. Therefore, the program uses a tag called Gcrun to indicate whether the garbage collector has started running. Using the second tag
