ReentrantLock source code analysis for Java concurrent Series Before Java5.0, only synchronized and volatile can be used to coordinate access to shared objects. We know that the synchronized keyword implements the built-in lock, while the volatile keyword ensures the multi-thread memory visibility. In most cases, these

written earlier: Java Collection HashMap source code Analysis Data Structure Above is the logical storage structure of the CONCURRENTHASHMAP, hash table (table) for hashing, table can be stored in the location of a linked list, but also may be a red-black tree.From this logical structure, if based on simple

understanding of string and the source code analysisHere I answer a xiaoguanzi, why just said string and char are closely related. Because the Java string is a sequence of char values (which is actually the final char array). This is well documented in the source code:/***/

Annotations to be processed, and the parameter env represents the current or previous run environment, and the process function return value indicates whether this set of Annotations is accepted by this Processor. If the rocessor of the subsequent child is accepted, the annotations will not be processed again.Reference[1]. The java™tutorials:http://docs.oracle.com/javase/tutorial/java/annotations/[2]. apt:

Java-source code analysis Today, when I checked the source code of the listing list, I encountered a pitfall. When I studied the source code

Recently, the time to take the Java Arrays Tool class Aslist method to do the source code analysis, the online collation of relevant information, recorded down, hope can also help readers! The Arrays tool class provides a method Aslist, using this method You can convert a variable-length parameter or array into a lis

Source code analysis of the collections list of Java Collection SeriesI. Introduction to tranquility list A sort list is an ordered sequence that allows efficient insert and remove operations at any location. It is implemented based on a two-way linked list. Ps: Here is a question about whether or not the data structur

The java. util package contains a series of important collection classes. This article will start with analyzing the source code, thoroughly studying the internal structure of a collection class, and traversing the source code implementation of the iteration mode of the set.

first analyzes the difficulties and complex business logic of the core links of Internet manufacturers, and the concept of middle-range service, and then takes you to the advanced features of the concurrent programming framework disruptor, including serial parallelization operations, diamond operations, polygon operations and deep parsing of the underlying code, Multi-producer Multi-consumer model practical application. Let us have a more in-depth un

Today, while looking at the source code of LinkedList, I met a hole. I study the source, found LinkedList is a straight line of the linked list structure, but I search data in Baidu, about this part of the source code analysis, al

expansionFrom the Putval source code we can know that when inserting an element size is added 1, if size is greater than threshold, it will be expanded. Assuming that our capacity size is 32,loadfator 0.75, then the threshold is a = * 0.75,At this point, Insert 25 elements, and insert the 25 elements are in the same bucket, the data structure in the bucket is a red black tree, then there are 31 barrels is

a third-party implementation, it is similar to a table data structure, each call to next ( It points to the next database record, calling different GetXXX (String columnName) for different types of fields to get the value of the corresponding field for that record. In addition to these primary interfaces, JDBC provides a DatabaseMetaData interface that describes database properties and some type classes such as Date and exception classes. From the above ana
