c c garbage disposal

First, the JVM memory structureThe Java Virtual opportunity divides the memory into several different management areas, each of which has its own purpose, depending on the characteristics of different tasks and the use of different algorithms in garbage collection. The whole is divided into the following sections:Program Counter Register, JVM virtual machine stack (JVM Stacks), local method Stack (Native methods Stacks), Heap (heap), method areaSuch a

I recently read GC (Garbage Collector) related things and found several good articles. Although I was older (06 years old), it is worth reading, the GC (Garbage Collector) Here is mainly about flashplayer9. Even if the English language is poor, a very small number of statements are not translated, because I don't know how much it takes for everyone to wait. Welcome to the layout. ^_^ most of this article is

When it comes to garbage collection (garbage collection,gc), many people naturally connect it to Java. In Java, programmers don't have to worry about memory dynamic allocations and garbage collection issues, all of which are given to the JVM to handle. Garbage collection, as the name implies, frees up space for

This article focuses on garbage collectionAlgorithm. The garbage collection mechanism first appeared in the world's second-largest language, lisp, Jean E. sammet once said that one of the longest sharing of The LISP Language is a non-verbal feature, which represents the terminologies of the system's automatic memory processing approach-garbage collection (GC,

(a) The basic assumptions of the garbage collector (1) objects that have recently been allocated memory space are most likely to need to be freed. Before a method is executed, it is often necessary to allocate memory space for the object to which the method is used, and searching for the most recently allocated collection of objects helps to free up the amount of free memory space that is likely to be spent. (2) The longest-life object is least likel

Speaking of garbage collection (garbage collection,gc), most people regard this technique as the companion product of the Java language. In fact, the history of GC is far longer than that of Java, and the 1960 birth of Lisp in MIT was the first language to actually use memory dynamic allocation and garbage collection techniques. When the list is still embryonic,

Java garbage collection mechanism JDK 5 provides four different garbage collection mechanisms: Serial collection, generational collection, parallel collection, and concurrent mark-clear collection. Java garbage collector is responsible for completing three tasks: allocating memory, ensuring that the memory of referenced objects is not recycled incorrectly, and re

Once a class is defined, we can new any number of objects. At this point, the memory allocation on the managed heap and stack is generated, and the heap will open up a new space to store the class object, and the stack simply stores the reference. In general, garbage collection and memory management are only relative to the managed heap. The memory management of C # is very convenient-that is, the garbage c
