Product Description
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
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.

that it is the only one that opened my eyes
in this excellent part of Java it is worth the money.
The book explains the concepts with simple (but not naive)examples. The new features of Java that this book explained
made me to write an excellent Master Thesis and also to
make Java to work with an application that had to work
in Real-Time. I have a Master in Control Engineering
and also one in Computer Science and I am doing another
in Biomedical Engineering. That book was the most usefull
book in all my 9 years of graduate and postgraduate studies.
And for that it takes 5 stars.
Other than the examples, the author does a reasonable job of explaining the APIs and as there are not too many books on NIO, it's nice to read something about it.
The thing that really struck me after reading this book and searching the web are some of the troubles developers are having with Java NIO API. There have been quite a few bugs (some of which have been fixed by Sun) and quite a few different ways to achieve the same result. Furthermore, there are frameworks out there to simplify using Java NIO (i.e. Apache MINA).
