Java Garbage Collector standard explanation and usage, java garbage collectionOverview When talking about Garbage Collection (GC), most people regard this technology as a companion product of the Java language. In fact, GC has a long history than Java. The Lisp, which was born on MIT in 1960, is the first language that

Master three garbage algorithms, seven garbage collectors, and learn what garbage collection algorithms are used for each garbage collector, as well as knowledge points about SafePoint.garbage Collection Algorithm1. Tag-purge algo

First, garbage collection mechanism-GCJavaScript has an automatic garbage collection mechanism (Gc:garbage collecation), which means that the execution environment is responsible for managing the memory used during code execution.Principle: The garbage collector periodically

The current commercial virtual machine garbage collection uses the "generational collection" algorithm, that is, according to the different life cycle of the object, divided into several pieces of memory, generally for the Cenozoic and the old era, different generations according to its characteristics of the use of the most appropriate

Chapter 5 JVM garbage collector (1): jvm garbage collection (The garbage collection algorithm is a theory, and the garbage collector is a collection algorithm. For details about the

-GC of waste recycling mechanism JavaScript has an automatic garbage collection mechanism (Gc:garbage collecation), in other words, the execution environment is responsible for managing the memory used during code execution. Principle: The garbage collector periodically (periodically) identifies those variables that are not being used, and then releases their m

　　Based on the "in-depth understanding of Java Virtual Machines", this book summarizes　　I. About several concepts: (tag garbage algorithm, garbage collection algorithm, garbage collector)There are two ways to find JVM garbage: The reference counting method/accessibility algo

What are the common garbage collectors in Java?In fact, the garbage collector (Gc,garbage Collector) is closely related to the specific JVM implementations, and different vendors (IBM, Oracle), different versions of the JVM, offer different choices. Next, I'll talk about the most mainstream Oracle JDK. Serial GC It is the oldest

Bibliography: In-depth understanding of Java Virtual Machine Zhou ZhimingJava Programming Ideas Bruce EckelWhy do we need to know about GC after automated garbage collection: When we need to troubleshoot various overflow, memory leak issues, when garbage collections become a bottleneck for the system to reach a higher concurrency, we have to implement the necessa

JVM-Garbage Collector, jvm-garbage collection This article mainly introduces several JVM garbage collectors. As shown below, the three above are the new generation collectors, The following three are the collectors of the old generation. The G1 collector can be used for the collect
