NIO and IO in the java file system, and nioio in the java File System Java introduced the java NIO mechanism since jdk1.4: The notable features of NIO are channel, buffer, selector ), n

First, the concept NiO is the new IO, the library is introduced in JDK1.4. NiO and IO have the same effect and purpose, but the implementation is different, NIO is mainly used in blocks, so the efficiency of NIO is much higher than IO. Two sets of NIO are provided in the

Introduction to Java NIOI/OI/O or input and output refers to the interface between the computer and the outside world or between a program and the rest of the computer. It is critical for any computer system, so the body of all I/O is actually built into the operating system. Separate programs generally allow the system to do most of the work for them.In Java programming, I/O has been completed until recent

Java NiO and Io After learning the Java NIO and IO APIs, a problem flooded into my mind: When should I use IO and when to use NIO? In this article, I'll try to clearly parse the differences between Java

Java NiO (new IO) is also a new feature introduced in JDK 1.4. Another important feature of JDK 1.4 is that regular expressions are often used, but NiO may be used, probably because the old Io system is still enough. For example, jdk1.5 has long been generic and annotated, but it is impossible to practice generics and annotations for various reasons.

The above mainly explains the Java IO class and how to use it, this article mainly about the NIO principle.NiO principleBlocking IONon-blocking and blocking is what we often call Io and nio. Before we talk about non-blocking, let's take a look at the blocking in the network communication.Common network IO communication flowsAbove is a network communication IO flo

The BufferedReader described in http://my.oschina.net/u/2263278/blog/508770 refers to one of its characteristics----when BufferedReader reads data from the input stream, if no valid data is read , where the program will block execution of the thread (using the Read () method of InputStream to fetch data from the stream, it will block the thread if there is no data in the data source), that is, the input stream described earlier, the output stream is blocked input, output. The traditional input a

After learning the Java NIO and IO APIs, a problem flooded into my mind: When should I use IO and when to use NIO? In this article, I'll try to clearly parse the differences between Java NiO and Io, their usage scenarios, and how they affect your code design. The main diffe

In JDK, there is a very interesting Library: NiO (New I/O ). This library has three important classes: Selector and channel in Java. NiO. channels and buffer in Java. NiO. This articleArticleFirst, let's take a look at why NiO i

ProgrammingThe java.nio.* package in JDK 1.4 introduces a new Java I/O library, which is designed to increase speed. In fact, "old" I/O packages have been re-implemented using NIO, which can benefit even if we don't explicitly use NIO programming. The increase in speed can occur in both file I/O and network I/O, but this article discusses only the latter.2.1. In
