GC Algorithm Garbage Collector overviewGarbage collection Garbage Collection is often referred to as the "GC", which was born in the 1960 MIT Lisp language, and has matured for more than half a century.In the JVM, the program counter, virtual machine stack, and local method stack are all born with threads, and stack frames are loaded and out of the stack with the entry and exit of the method, and automatic memory cleanup is realized, so our memory gar

The garbage collector is a specific implementation of memory recycling, the Java virtual machine specification does not specify its implementation, different vendors, different versions of the virtual machine provides a large variety of garbage collectors. This article mainly introduces the garbage collector in the HotSpot virtual machine.Various garbage collectorsShows different garbage collectors, each of

This article is based on Zhou Zhiming's "in-depth understanding of Java virtual machines"If the collection algorithm is the method of memory recycling, the garbage collector is the specific implementation of memory recycling. There is no provision for how the garbage collector should be implemented in the Java Virtual Machine specification, so different vendors, different versions of the virtual machines, m

Read the Java Paper garbage collector type article, here to do a summary, the article part of the translation from the Java Paper GC collector, part of the summary of their own, the image from the network, which is only used to understand the expression.One, JVM GC garbage collector typeThe JVM's garbage collector is b

If the collection algorithm is the method of memory recycling, then the garbage collector is the specific implementation of memory recycling. In the Java Virtual Machine specification, how the object garbage collector should be implemented does not have any rules, so different vendors, different versions of the virtual machines provided by the collector may be qu

http://blog.csdn.net/java2000_wl/article/details/8030172 Click on the Open link HotSpot JVM Collector There are 7 collectors, divided into two, the new generation of collectors, the following is the old age collector. If there is a connection between the two collectors, it means they can be used in combination.serial (serial GC) collectorThe serial collector is

ObjectiveThe garbage collection algorithm has been described in more detail here, we will introduce the specific garbage collector in the JVM, in the virtual machine specification is not how to implement the garbage collector, so each manufacturer's garbage collector may be completely different, However, we are introducing the JDK1.7-based hotspot virtual machine

1. Serial Collector The serial collector is a single thread collector, but its "single-threaded" meaning does not simply mean that it uses only one CPU or a collection thread to do the garbage collection, and more importantly, when it does garbage collection, all the other worker threads must be paused until the collection is complete. Serial

Introduction Garbage collection technology is not the Java language Initiative, the 1960 was born at MIT Lisp is the first real use of memory dynamic allocation and garbage collection technology language. Three issues to consider for garbage collection technology are: 1. Which memory needs to be recycled 2. When to recycle 3. How to Recycle The distribution of Java Memory Runtime regions, where program counters, virtual machine stacks, and local method areas are all born with threads, and a

New generation collectors for hotspot virtual machines There are seven main types of hotspot garbage collectors: As shown in the picture:The upper part of the figure is the new generation of garbage collectors, the following section represents the old age of the garbage collector, the two garbage collector between the line means that two collectors with the use.

Garbage collector Garbage collector for hotspot virtual machines There is no provision in the Java Virtual Machine specification for how the garbage collector can be implemented, so different versions of the virtual machine provide a large difference in the garbage collector, and will provide the paramet

with the thread, and out of the thread, so that the memory allocation and recovery of these areas are deterministic, there is no need to too much consideration of the recycling problem, because the end of the method or the end of the thread, memory naturally with the recycling. The Java heap and method areas are different and different! (How not to say the catchy), this part of the memory allocation and recycling is dynamic, it is the garbage collector
