In Java Number Cruncher, author Ronald Mak explains how to spot-and how to avoid-the subtle programming miscues that can cause vexing calculation errors in your applications. An authority on mapping pure math to computer math, he explains how to use the often-overlooked computational features of Java, and does so in a clear, non-theoretical style.

Without getting lost in mathematical detail, you’ll learn practical numerical algorithms for safely summing numbers, finding roots of equations, interpolation and approximation, numerical integration, solving differential equations, matrix operations, and solving sets of simultaneous equations. You’ll also enjoy intriguing topics such as searching for patterns in prime numbers, generating random numbers, computing thousands of digits of pi, and creating intricately beautiful fractal images.

Java Number Cruncher includes:

*Practical information all Java programmers should know
*Popular computational algorithms in Java-without excessive mathematical theory
*Interactive graphical programs that bring the algorithms to life on the computer screen
*Rounding errors, the pitfalls of integer arithmetic, Java’s implementation of the IEEE 754 floating-point standard, and more
*This book is useful to all Java programmers, especially for those who want to learn about numerical computation, and for developers of scientific, financial, and data analysis applications.

This book features step-by-step examples in major game programming
areas such as graphics, GUI, networking, tiles, animation, and sound.
Additionally, the book goes into some detail about the business model
of wireless game distribution.

devices running Symbian OS. This book provides the most comprehensive
developer guide yet for the most advanced mobile Java environment
available: Java MIDP 2.0 on Symbian OS.

This book provides an overview of Java MIDP 1.0 and - using the world’s
first MIDP 2.0 phone - the platform enhancements developers can exploit
in the coming wave of Java MIDP 2.0-based smartphones. With in-depth
case studies and sample code throughout, it equips developers with the
knowledge they need to fully exploit the powerful applications platform
Symbian OS provides.

The elegant, powerful architecture of
Symbian OS is optimized for the mobile environment. Whether you are
developing applications and services for currently available mobile
phones, or involved in pre-market mobile phone development, this book
will give you an understanding of the fundamental theory behind
developing Java applications for Symbian OS phones.

Symbian OS
is the advanced, customizable operating system licensed by the world’s
leading mobile phone manufacturers. It is designed for the specific
requirements of advanced 2.5G and 3G mobile phones and includes a
robust multitasking kernel, integrated telephony support,
communications protocols, data management, advanced graphics support, a
low-level graphical user interface framework and a variety of
application engines.

Programming Java for Symbian OS is part of the Symbian Press series;
written by Symbian OS software engineers, titles in the series are
replete with expert knowledge that will allow the reader to develop
better software, faster.

As mobile working becomes a reality, understanding Symbian OS is a key skill
for enterprise and IT developers. This book is a must-have resource for developers
that wish to create applications that utilize both the mobility of Symbian OS
and the raw power of the desktop. It introduces the APIs, patterns and issues
involved in developing applications that run on a Windows PC and integrate with
Symbian OS phones - including developing specialized servers on the Symbian OS
phone.

In conjunction with the relevant SDKs, Programming PC Connectivity Applications
for Symbian OS will enable an experienced developer to speedily create a basic
Connectivity application and be in position to take advantage of other books

“Kuchana � does a good job contrasting patterns that may seem similar
to the novice. � This is a useful addition to a collection on software
design patterns. ” - CHOICE, Feb. 2005, Vol. 42, No. 06 “Why am I so
pleased with this book? What makes it any different than other design
pattern books? Well, first of all the volume is huge. Kuchana’s book
covers all the original Gang of Four patterns plus another 20 or so
patterns, including a couple of multithreading related patterns.
Second, the text itself is very readable and doesn’t cling too much on
fancy words. The explanations are concise and to the point�All in all a
very good choice for filling the gaping design patterns encyclopedia
slot in your bookshelf. Highly recommended.” “Partha Kuchana is an
experienced Enterprise Systems Architect. He understands that patterns
are not about things that are just good ideas, but that patterns are
about capturing knowledge bred from experience. This hard-won knowledge
is what Partha is sharing with readers of his book�Keep it handy for
all those ‘How do I do this in Java?’ questions where you wish you had
an expert in the office next door to provide answers. This book is the
next best thing.” Linda Rising, from The Foreword

At the end of the day, Web services aren’t hard to conceptualize.
They’re just a bunch of software modules with specific rules about how
they go about discovering one another and sending messages back and
forth. Implementation is another story, however. In the Java language,
writing Web services requires an understanding of half a dozen
specialized APIs at minimum, and more than that if you want to do
fancier stuff. Java Web Services does a very good job of dispersing the confusing terminology (and obfuscating hype) and of showing you exactly how to do
Web services work in Java. This doesn’t sound like a revolutionary
concept, but unfortunately it is. David Chappell and Tyler Jewell have
comfortably fit into less than 250 pages what others have not done as
well in twice as much space.

Take Universal Description, Discovery,
and Integration (UDDI) work as an example. UDDI exists to help software
locate other software that does what it wants. How do you do that?
Chappell and Jewell present two concise program listings–a client and
a server–that show how to do a UDDI lookup. They then refine their
code by using a third-party API that makes the work easier. Similarly
pragmatic attention goes to Simple Object Access Protocol (SOAP), in
which they show how to create a message, populate it with XML, make an
attachment if necessary, and send it on its way. You won’t find a lot
of frills or conceptual explanations (though there are enough “why”
sections to ensure that you’re not just typing recipes blindly); the
emphasis is on writing Java code that interacts with Web services
protocols and standards. –David Wall

Topics covered:
How to write Web services software in Java, with respect to Universal
Description, Discovery, and Integration (UDDI), Simple Object Access
Protocol (SOAP), and Web Services Description Language (WSDL). There’s
also coverage of interprocess communication under JAX-RPC and ways to
implement security. All of the low-level stuff is here. Look elsewhere
for architecture and design information.
