NIO Tutorial - Java NIO Tutorials

In this section we will discuss about the Sun java nio package. This nio tutorials will help you learn nio package with examples. We are providing many examples on the Java nio package here. You can download and use the examples to learn and explore the java nio package.

NIO Package:

The java.nio package was first included in the JDK 1.4 to help the programmer to write fast programs. This package is part of JDK 1.5 and JDK 1.6 also. It provides improved performance in buffer management, scalable network and file I/O, character-set support and the regular-expression matching. The sub packages of the java.nio package are:

  1. java.nio
  2. java.nio.channels
  3. java.nio.channels.spi
  4.  java.nio.charset
  5.  java.nio.charset.spi
  6. java.util.regex

Here are the features of NIO API:

  1. It provides the buffers for data of primitive types
  2. It provides Charcter-set encoders and decoders
  3. The support for Perl-style pattern matching using regular expressions
  4. It introduces the Channels, which a new primitive I/O abstraction
  5. A file interface supporting locks and memory mapping
  6. Support for multiplexed, non-blocking I/O for writing scalable servers

The NIO API provides many useful abstraction classes to better programming. The useful abstraction classes are:

  1. Buffers
  2. Charsets
  3. Channels
  4. java.nio.channels.spi
