Java Nio ReviewI bought this book because of the lack of material on java.nio.
The book is a good introduction to java.nio but that is the extent of it. Half the book is an api reference and regular expressions (why is this even covered in this book?).
The rest tells you a little bit about the API, but not how to use it. There are examples, but you have to download them from the internet (ie no CD with the book).
The best chapter you can download for free anyway, so don't bother buying the book. Just download the free chapter and the free examples. The material on the internet from this book covers 90% of what you need to know.Java Nio 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.
