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. Technical background you need to know.
Second, which memory needs to be recycled?
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 the subsequent collection algorithms are based on this idea and the shortcomings of the imp
Detailed description of JVM memory partition and garbage collection mechanism, jvm garbage collection
When writing Java code, you do not need to worry about whether your New object is released or when. Because the JVM has an automatic garbage collection mechanism. In our previous blog, we talked about the MRC (manual reference counting) and ARC (automatic referen

, although the end of an object can ensure that the object can clear unmanaged resources, it is still inherently uncertain, and the second phase will become quite slow due to additional background processing.

Many unmanaged resources are very valuable, so they should be cleared as quickly as possible, although they can be cleared during garbage collection through the finalize () metho

The GC module of Python uses reference counting to track and recycle garbage. Based on the reference count, you can also use mark and sweep to solve the possible circular reference problem of container objects. The generation collection is used to increase the effic

During the development of. NET programs, since the garbage collection mechanism in CLR manages allocated objects, programmers can ignore the time when objects are released. However, it is necessary to understand the

JVM garbage collection mechanism and jvm garbage collection
Scope: areas to be recycled
Among the five JVM memory models, three do not require garbage collection: Program counters, JVM stacks, and local method stacks. Because their lifecycle is synchronized with the thread, the memory they occupy will be automatically released as the thread is destroyed,There
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
Java garbage collection mechanism and java garbage collection
When it comes to Garbage Collection (GC), many people naturally associate it with Java. In Java, programmers do not need to worry about the problem of dynamic memory allocation and garbage collection. All this is handled by JVM.
As the name implies,
We all know the Java garbage collection mechanism, Java has its own garbage collector to automatically recycle garbage. I have been aware of the garbage collection mechanism before the Java garbage collector is automatically recycled gar

Today we will study Java virtual machines using garbage collection algorithms and common garbage collectors. The program counters, virtual machine stacks, and local method stacks of the Java Virtual Machine memory area are 3 regions that are born with threads, are out of thread, and stack frames in the stack follow the method's entry and exit stack and stack. The amount of memory allocated in each stack fra
