Data Structures and Algorithms With Object-Oriented Design Patterns in Java - This book is about the fundamentals of data structures and algorithms--the basic elements from which large and complex software artifacts are built. To develop a solid understanding of a data structure requires three things: First, you must learn how the information is arranged in the memory of the computer. Second, you must become familiar with the algorithms for manipulating the information contained in the data structure. And third, you must understand the performance characteristics of the data structure so that when called upon to select a suitable data structure for a particular application, you are able to make an appropriate decision.

Securing Java - We hope this book appeals to geeks and grandmothers alike (not that some grandmothers aren't geeks). Although it gets technical in places, we hope the messages are clear enough that even the casual Web user comes away with a broader understanding of the security issues surrounding mobile code. We kept four groups in mind as we wrote this book: Web users, developers, system administrators, and business decision-makers. Many of the issues of mobile code security cut across these groups. As Java integrates itself into the foundations of electronic commerce, Java security issues take on more urgency.

JXTA - This book presents a guided tour of the JXTA platform, including all of the critical information required to begin producing P2P solutions built on top of JXTA. Reference information on each of the JXTA protocols provides an understanding of the underlying principles of P2P networking, and examples built on the JXTA reference implementation provide the hands-on experience necessary to become fluent in JXTA technology.
