After learning the APIs for Java NIO and io, a problem immediately poured into my mind:When should I use IO and when do I 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.

Java NiO mainly consists of the following core components: Channel Cache Selector SelectorJava NiO actually has more classes and components than the above, but in my opinion, Channel,buffer,selector is the core API. Other components, like pipelines and file locks, are simply generic tool classes that are used in conjunction with the three core co

Last update: 2015-04-15This Java NIO files Class (Java.nio.file.Files) provides several methods for manipulating files in a file system. This Java NIO files Class tutorial will cover the use of most common methods of these methods. This class contains many methods, so you can also check the Javadoc if you need a method
Java NiO is similar to traffic, but with some differences:• The channel can read and write, and the stream only supports unidirectional. Read or write• Asynchronous channel Read• Channel reader, they are alternating with bufferThe realization of the TaoThe following is the implementation of the most important channel in Java
The buffer of Java NiO is used to interact with the channel.Buffer is essentially a block of memory, you can write the data and then read it out.This block of memory is wrapped by NiO's buffer object, which provides a series of methods that make access to the block of memory much easier.Basic buffer UseReading and writing data using buffer generally has the following 4 steps:1. Write Data to Buffer2. Call t
Last update time: 2014-06-23A Java NiO pipeline is a one-way data connection between two threads. A pipe has a source channel and a sinking channel. You write data to a sinking channel. This data is then read from the source channel.Here's a plumbing principle:Create a pipelineYou can open a pipeline by calling the Pipe.open () method, like this:Pipe pipe = Pipe.open ();Write a pipelineIn order to write a p

Public abstract int write (bytebuffer SRC) writes the byte sequence from the given buffer to this channel.Public abstract int read (bytebuffer DST) reads the byte sequence from this channel into the given buffer zone.

In Java NiO, if one of the two channels is FileChannel, you can transfer the data directly from one channel (translator note: Channel Chinese translation channels) to another channel.Transferfrom ()The Transferfrom () method of the FileChannel can transfer data from the source channel to the FileChannel (translator Note: This method is interpreted in the JDK document as the transfer of bytes from a given re
The Datagramchannel in Java NiO is a channel that can send and receive UDP packets. Because UDP is a non-connected network protocol, it cannot be read and written like other channels. It sends and receives a packet.Open DatagramchannelHere's how Datagramchannel is opened: 1 DatagramChannel channel = DatagramChannel.open(); 2 channel.socket().bind(newInet
Java NiO began to support Scatter/gather,scatter/gather to describe the operation of reading or writing to the channel from the channel (the translator notes: Channels are often translated in Chinese).Dispersion (scatter) reads from the channel means that the data read is written to multiple buffer during a read operation. As a result, the channel will "scatter" (scatter) the data read from the channel into
Java basics-New I/O technology (NIO) and basics nioBefore JDK1.4, I/O input/output processing is called the old I/O processing. Beginning with JDK1.4, java provides a series of improved new input/output features, these functions are called new I/O (new I/O) and many NEW classes are added for processing input/output.Java. nio
