With these problems, it is urgent for some of them to develop a universal framework to facilitate working class. The most deadly NIO framework is Mina and Netty, which has to be said in a small episode:First look at MINA 's main contribu
IO does not have much to do with multithreading, but NIO changes the way threads are used at the application level and solves some of the practical difficulties. AIO is also somewhat related to the asynchronous IO and the previous series. Here, in order to learn and record, also write an article to introduce NiO and AIO.
1. What is NiO
Java NIO Study Notes
The project team is engaged in IM products, and the server certainly uses NIO technology as the communication bottom layer. However, I have always been familiar with some NIO theories and have no practice. Now I am free to practice NIO.

Recently, Java NiO (New I/O) is the most important part of Java development due to working relationships. Although I have learned a little about it before, however, I have not carefully read its implementation principles and have no chance to use them at work. This time I will study it again. By the way, I should take a note of learning
Tag: COM generates transmission class www. Why is the device operating system logWhy should NIO use NIO?NIO was created to enable Java programmers to implement high-speed I/O without having to write custom native code. NIO transfers the most time-consuming I/O operations (th

Java handles large files, generally with bufferedreader,bufferedinputstream such as buffered IO classes, but if the file is oversized, the faster way is to use Mappedbytebuffer.Mappedbytebuffer is a File memory mapping scheme introduced by Java NIO, which is very high in read and write performance. The main thing about NIO

When learning Java NIO and IO APIs, a problem quickly emerges in the brain:When to use IO? When to use NiO?The author of this article will try to clarify some of the differences between Java NiO and Io, their use cases, and how they each affect our code design. The main diff
Introduction to NIOIn the previous period of time in the company to deal with some big data, and its word segmentation, extraction of keywords and so on. Although the task is basically completed (the effect is not particularly good), for Java has not been introduced to me for 2 weeks, and I was drunk. Of course, there are knowledge related to machine learning, I would like to continue to record the process of my task, but also to do a summary. First o
Java Nio:nio OverviewSeveral IO models were described in the previous blog post, and now we are starting to get into the Java NIO Programming topic. NIO is a new API in Java 4 that is designed to solve the problem of traditional IO. The following are some basic concepts from
Brief Introduction
Java NIO is an asynchronous IO introduced by Java 1.4.Java NIO consists of the following core components:-Channel-Buffer- comparison of Selector NIO and IO

ScenarioThe server needs to support an extremely large number of long-time connections . For example, 10,000 connections above, and each client does not frequently send too much data . For example, a central server in a head office needs to collect the transaction information of each register at a national convenience store, requiring only a small number of threads to handle the long-term connection of maintenance on demand.Jetty, Mina, Netty, zookeeper, etc. are all based on the
Original: http://www.cnblogs.com/dolphin0520/p/3916526.htmlBefore entering Java NIO programming, let's discuss some basic knowledge: I/O models. The following first starts with the concept of synchronous and asynchronous, then explains the difference between blocking and non-blocking, then introduces the difference between blocking IO and non-blocking IO, then introduces the differences between synchronous
