As we know that Java NIO supports multiple transaction from and to channels and buffer.So in order to examine one or more NIO Channel’s, and determine which channels are ready for data transaction i.e reading or writing Java NIO provide Selector. With Selector we can make a thread to know that which channel is ready…

Buffers in Java NIO can be treated as a simple object which act as a fixed sized container of data chunks that can be used to write data to channel or read data from channel so that buffers act as endpoints to the channels. It provide set of methods that make more convenient to deal…

As we know that Java NIO is a more optimized API for data IO operations as compared to the conventional IO API of Java.One more additional support which Java NIO provides is to read/write data from/to multiple buffers to channel.This multiple read and write support is termed as Scatter and Gather in which data is…

Java NIO server socket channel is again a selectable type channel used for stream oriented data flow connecting sockets.Server Socket channel can be created by invoking its static open() method,providing any pre-existing socket is not already present.Server Socket channel is created by invoking open method but not yet bound.In order to bound socket channel bind() method is to be…

Java NIO socket channel is a selectable type channel which means it can be multiplexed using selector, used for stream oriented data flow connecting sockets.Socket channel can be created by invoking its static open() method,providing any pre-existing socket is not already present.Socket channel is created by invoking open method but not yet connected.In order to connect socket…

Java NIO Datagram is used as channel which can send and receive UDP packets over a connection less protocol.By default datagram channel is blocking while it can be use in non blocking mode.In order to make it non-blocking we can use the configureBlocking(false) method.DataGram channel can be open by calling its one of the static…

Description As already mentioned FileChannel implementation of Java NIO channel is introduced to access meta data properties of the file including creation, modification, size etc.Along with this File Channels are multi threaded which again makes Java NIO more efficient than Java IO. In general we can say that FileChannel is a channel that is connected…

Description As name suggests channel is used as mean of data flow from one end to other.Here in java NIO channel act same between buffer and an entity at other end in other words channel are use to read data to buffer and also write data from buffer. Unlike from streams which are used in…

As we know that java NIO is introduced for advancement of conventional java IO API.The main enhancements which make NIO more efficient than IO are channel data flow model used in NIO and use of operating system for conventional IO tasks. The difference between Java NIO and Java IO can be explained as following −
