Pro Java 7 NIO.2

Book description

Pro Java 7 NIO.2 addresses the three primary elements that offer new input/output (I/O) APIs in Java 7, giving you the skills to write robust, scalable Java applications:

An extensive file I/O API system addresses feature requests that developers have sought since the inception of the JDK

A socket channel API addresses multicasting, socket binding associated with channels, and related issues

An asynchronous I/O API enables mapping to I/O facilities, completion ports, and various I/O event port mechanisms to enhance scalability

NIO.2 for the Java platform, known as JSR 203, is a major feature of the new Java JDK 7 under the leadership of Alan Bateman as an OpenJDK project. Take advantage of these exciting new developments with Pro Java 7 NIO.2.

What you'll learn

How to carry out Path class operations

How to get/set file metadata through the java.nio file attribute API (including POSIX)

How to manage symbolic and hard links (including create, delete, and find target)

How to deal with files and directories through the new java.nio.file.Files API

How to use the FileVisitor API to develop file recursive operations

How to explore the Watch Service API and file change notification

How to use the new SeekableByteChannel API for Random Access File

How to develop blocking/non-blocking socket-based applications

How to explore the jewel of NIO.2: the Asynchronous Channel API

How to use the Zip File System Provider and write a custom file system provider

How to refactor code
