not: reference counting method and the algorithm of accessibility analysis . Reference Counting Method The logic of the reference counting method is very simple, but there is a problem, Java does not use this way to make object survival judgments. The logic of the reference notation is to maintain a counter counter at the head of the object when it is stored in the heap, and counter++ if an object adds a r

Java list source code analysis, list source code analysis Three Data Structure linked lists, trees, and graphs. As one of them, the sequence table is the longest used in programming. The List interface is the implementation of sequence tables in java. It has many subinterfaces and implementation classes, which are very

user login, output user information, manage cart, etc. ; Other session EJBs provide some common methods, such as generating unique identifiers, and so on. The traditional JavaBean component has evolved into a value object, transferring data between EJB components and applications, successfully processing the encapsulation of each object, effectively reducing the difficulty of programming. XML document classes are used to process order information. The WAF of this example is an effective implem

Java concurrent series of AbstractQueuedSynchronizer source code analysis (summary analysis ), To learn Java concurrent programming, you have to understand the java. util. concurrent package. This package contains many frequently used concurrent tool classes, such as Reentra

Dynamic proxy principle (for sample code, see Java reflection mechanism analysis (3 )) A) understand the process of the above dynamic proxy example B) proxy interface implementation class source code analysis Let's take a look at the source code of the proxy implementation class ($ proxy0) and the entire dynamic proxy process. The code generated by $

Learn Java concurrency programming have to understand java.util.concurrent this package, this package has many of the concurrency tools we often use, such as: Reentrantlock, Countdownlatch, Cyclicbarrier, Semaphore and so on. The underlying implementations of these classes depend on the Abstractqueuedsynchronizer class, which shows the importance of this class. So in the Java Concurrency Series I first abst

In-depth analysis of Java I/O class features and application scenarios, in-depth analysis of application scenarios There are more than 40 classes related to input and output in Java. If the relationship between them is not clarified, they cannot be used flexibly. If the stream flow is divided, it can be divided into th

Yesterday I wrote a simple chat about the simple memory partitioning of the Java Execution program, and today we'll talk about memory analysis of static variables and methods.The first feature of 1.static variables and methods memory analysisThe first attribute of the STATIIC variable and method is called by the class name, the static variable, and the class name. The static method is invoked in the form of

[Java Collection source code analysis] TreeMap source code analysis Reprinted please indicate the source: http://blog.csdn.net/ns_code/article/details/36421085 Preface This article does not intend to extend the style of the previous articles (add comments to all source code), because we need to understand all the source code of TreeMap. For bloggers, it really ta

from Destpos to Destpos+length-1. Because it is a native method, it is not visible in the JDK, but you can view the source code in the OPENJDK. The function actually eventually calls the C language's memmove () function, so it can guarantee the correct copying and movement of elements within the same array, which is much more efficient than the general method of replication, and is well suited for batch processing of arrays . Java strongly recommends

Objective This article does not intend to extend the previous several styles (add the annotation to all source code), because to understand all the source code of TreeMap, for bloggers, it does take a lot of time and experience, it seems unlikely to have so much time to invest, Therefore, this is intended to be through the reading source to the TreeMap has a macro grasp, and some of the implementation of some methods to do a more in-depth analysis.
