When I was a beginner at JSP, I wrote some tool functions because I could not use the regular expressions in JAVA! Let everyone criticize and give some comments! There are a few functions that you don't want to write! I'm a newbie. I'm afraid of

The following is transferred from http://ifeve.com/anatomy-of-a-synchronizer/:Although many synchronizers (such as locks, semaphores, blocking queues, etc.) function differently, their internal design is very different. In other words, the

I have translated an article about the Java read/write lock, because I have never read the related content of the read/write lock before. Here, even if I have learned and translated it, it may not be accurate! Well, let's talk less about it. Let's

Hashtable of Java source code 1. Hashtable Overview Class implements a hash table, which maps the key-key object to the corresponding value object. Both key and value are requiredNon-null. To successfully store and obtain objects in a hash table,

Today happened to see this thing, has been looking at other people's data, decided to personally look at the source code. The JDK version is 6.0_04 1 statements without any distinction public class ArrayList extends AbstractList implements List,

Part 1th Vector IntroductionVectors are vector queues, which are classes added by the JDK1.0 version. Inherits from Abstractlist, implements the list, randomaccess, cloneable these interfaces.Vector inherits the Abstractlist and realizes the list;

The previous article has translated the Hashtable source code top annotation, this article will explain in detail Hashtable each method realization. Hashtable Hierarchy Chart Let's look at the definition of Hashtable: public class Hashtable extends

Data sharing among multiple threads1. The word atomic of Synchronized has nothing to do with "atom". It was once considered to be the smallest unit of matter and cannot be split into smaller parts. When a method is declared as synchronized, the

Basic working principle of Connection Pool 1. Basic Concepts and Principles From the above analysis, we can see that the root cause of the problem is the inefficient management of database connection resources. We know that there is a well-known

Sharing data issues between multiple threadsFirst, SynchronizedkeywordThe word atomic is not related to "atoms", it was previously thought to be the smallest unit of matter and could no longer be disassembled into smaller parts. When a method is

Copy Code code as follows: Public synchronized void Run () { } As you can see from the above code, as long as you add the synchronized keyword between void and public, you can synchronize the Run method, that is, for an object

Code reviews are one of the most important ways to eliminate bugs, which are especially effective in most cases. Because the code review itself targets objects, it is to overlook the problems and bugs of the entire code in the test process. In
