garbage. The reason for separating them is to divide and conquer them. Based on the characteristics of memory blocks in different regions, different memory recovery algorithms are adopted to improve the efficiency of garbage collection in the heap area. The following is a detailed introduction. II. Introduction to common memory recovery Algorithms The above is

that the object is assigned to be empty, it must be marked as recyclable, and it is possible that escape will occur. 1.2. Now let's take a look at some of the garbage collection algorithms 1.2.1. Before JDK1.2, the reference counter algorithm is used, That is, when this class is loaded into memory, a series of information such as method area, stack, program counter, etc. is generated, when objects are crea

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

PHP's garbage collection mechanism is very important in any development language, and PHP's garbage collection mechanism allows developers to avoid memory leaks as much as possible during the development process, and to automatically reclaim variables by reference counting, but there are still memory leaks in certain,

　　Garbage collection algorithm Tag-Purge algorithm The most basic algorithm is the tag-purge (mark-sweep) algorithm. There are two stages of marking and purging: first marking out all objects that need to be recycled, and then uniformly reclaiming all tagged objects when the tag is complete. It is the most basic collection algorithm, because t

The first thing to say is garbage, what's the name garbage?All is garbage, also first,second, I am not against who, everyone here is rubbish!!!HotSpotWTF, hot pots? What about my grandmother's heat, heat,you know?In short, the hotspot is a Java virtual machine to follow the specification of a realization, it was not sun company, but another company, was later acq

I believe in the same procedure. Apes often encounter garbage collection problems in their daily work or interviews, and are there any details in the dead of the dead of night on the JVM garbage collection mechanism? It doesn't matter if you don't have time to do it, because it will be smoothed out next. I. Te
