Overview

Many serious Java programmers, especially enterprise Java programmers, consider the new I/O API—called NIO for New Input/Output—the most important feature in the 1.4 version of the Java 2 Standard Edition. The NIO package includes many things that have been missing from previous editions of Java that are critical to writing high-performance, large-scale applications: improvements in the areas of buffer management, scalable network and file I/O, character-set support, and regular expression matching. Most of all, ...

Overview

Many serious Java programmers, especially enterprise Java programmers, consider the new I/O API—called NIO for New Input/Output—the most important feature in the 1.4 version of the Java 2 Standard Edition. The NIO package includes many things that have been missing from previous editions of Java that are critical to writing high-performance, large-scale applications: improvements in the areas of buffer management, scalable network and file I/O, character-set support, and regular expression matching. Most of all, it boosts performance and speed dramatically.Java NIO explores the new I/O capabilities of version 1.4 in detail and shows you how to put these features to work to greatly improve the efficiency of the Java code you write. This compact volume examines the typical challenges that Java programmers face with I/O and shows you how to take advantage of the capabilities of the new I/O features. You'll learn how to put these tools to work using examples of common, real-world I/O problems and see how the new features have a direct impact on responsiveness, scalability, and reliability. The book includes:

  • A rundown of the new features in NIO
  • Basic and advanced I/O Concepts
  • Binary I/O and the new buffer classes
  • Memory mapped files and file locking
  • Character I/O: encoding, decoding and transforming character data
  • Regular Expressions and the new java.util.regex package
  • Muliplexing with java.nio
Because the NIO APIs supplement the I/O features of version 1.3, rather than replace them, you'll also learn when to use new APIs and when the older 1.3 I/O APIs are better suited to your particular application.Java NIO is for any Java programmer who is interested in learning how to boost I/O performance, but if you're developing applications where performance is critical, such as game computing or large-scale enterprise applications, you'll want to give this book a permanent spot on your bookshelf. With the NIO APIs, Java no longer takes a backseat to any language when it comes to performance. Java NIO will help you realize the benefits of these exciting new features.

This title provides a complete introduction to this major improvement in the new 1.4 version of Java, the new Java.Nio package. It includes information missing from previous editions of Java that are critical to writing high-performance applications.

    BUY and READ this book!

    The new Java I/O API is dramatically important technology. Many books are likely to be written about it, but it's not likely there will ever be a better one. Hitchens writes with such charm and insight that his book is worth a look even if you think you have no interest in java.nio -- you may be pleasantly surprised. And, if you do need to know about Java's new I/O, you will be delightfully informed.

    This is the book you want for NIO!

    This is >THE< book for serious developers that want to master Java's new NIO API. This book is very well written and the author really turns a boring topic into something enjoyable. :) The examples are well written and aren't the typical fast hack 'em examples you see in most books these days. I highly recommend this book for anyone who seriously wants to make I/O-bound applications perform their best. Ron's knowledge of IO is amazing. You won't be disappointed!
