　　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 algorithm. This preparation, after marking the garbage, the recovery algorithm, where the algorithm is just garbage collection idea. There will be a variety of garbage collectors, the

　　What memory needs to be recycled?Java Memory Runtime area of the various parts, where the program counter, virtual machine stack, the local method stack 3 regions with the thread, with the thread, the stack frame in the stack with the method entered and exited with a non-flocculation of the execution of the stack and into the stack operation. How much memory is allocated in each stack frame is basically known when the class structure is determined. Therefore, memory allocation and recycling ar

The G1 garbage collector (G1 GC) is the newly introduced garbage collector for the Java HotSpot VM in JDK 7, and the Java SE 6 Update 14 already contains a G1 experience version (according to 51CTO earlier, when the Java SE 6 U14 debut in early June, the original Su The statement of N is: the G1 garbage collector needs to be used by the charging party. Soon after

garbage collector is concerned with this part of the memory.Heap memory for this large number of object instances, the garbage collector first infers which of these objects are "alive" and which are "dead"The reference counter algorithm adds a reference counter to the object and adds 1 to the counter whenever it is referenced. Calculator minus one when you lose a quote.At any given moment, a calculator val

What is a train collector? Train Collector is a professional Internet data capture, processing, analysis, mining software, Can quickly and easily crawl the Web page in a large number of unstructured text, pictures and other resource information, Then through a series of analysis and processing, accurate mining the required data. You can also choose to publish to a Web site background, import a database,

Collector, usually called the Thief program, is mainly used to crawl other people's web content. On the production of the collector, it is not difficult to open the Web page to be collected remotely, and then use regular expressions will need to match the content, as long as a little bit of regular expression of the basis, can make their own collector to. A few

Chapter 6 JVM garbage collector (2) jvm garbage collection The previous chapter records several common garbage collectors. For details, see chapter 5 JVM garbage collector (1). 1. G1 Note: From the Perspective, compared with CMS, G1 is different only in the final "filter and recycle" section (CMS is a concurrent cleanup). In fact, the overall heap memory division of the G1 recycler is different from tha

Garbage collection mechanism in JavaAn important feature of Java is the garbage collector, and the ability to automatically recycle garbage, which is the advantage of Java relative to other languages, such as the C language there is no automatic garbage collection mechanism.Every instance object and array in Java allocates space within the heap, the interpreter has the ability to allocate space for the class instance, and when the interpreter allocate

problem DescriptionThere is a collector who own many valuable jewels. He has a problem on how to store them. There is M special boxes. Each box has a value. And each of the N jewels have a value too.The collector wants to store every jewel in one of the boxs while minimizing the sum of difference value.The difference value between a jewel and a box is: |a[i]-b[j]|, A[i] indicates the value of i-th Jewel, B[

equivalent to passing forced, but future versions of the CLR may be modifiedForced: Forced collection of the specified generation (and less than its generation)Optimized only performs recycling if it can release large amounts of memory or reduce the amount of fragmentation. If the garbage collection is not performing well, the current call has no effect.In most cases, you should avoid calling any of the collect methods; it is best to have the garbage collec
