Description:

"One of the great things about the book is the
way the authors explain concepts very simply using analogies rather than
programming examples—this has been very inspiring for a product I'm working
on: an audio-only introduction to OOP and software development."
—Bruce Eckel
"...I would expect that readers with a basic
understanding of object-oriented programming and design would find this book
useful, before approaching design patterns completely. Design Patterns
Explained complements the existing design patterns texts and may perform a
very useful role, fitting between introductory texts such as UML Distilled and
the more advanced patterns books."
—James Noble
Leverage the quality and productivity benefits of
patterns—without the complexity! Design Patterns Explained, Second
Edition is the field's simplest, clearest, most practical introduction to
patterns. Using dozens of updated Java examples, it shows programmers and
architects exactly how to use patterns to design, develop, and deliver
software far more effectively.
You'll start with a complete overview of the
fundamental principles of patterns, and the role of object-oriented analysis
and design in contemporary software development. Then, using
easy-to-understand sample code, Alan Shalloway and James Trott illuminate
dozens of today's most useful patterns: their underlying concepts, advantages,
tradeoffs, implementation techniques, and pitfalls to avoid. Many patterns are
accompanied by UML diagrams.
Building on their best-selling First Edition,
Shalloway and Trott have thoroughly updated this book to reflect new software
design trends, patterns, and implementation techniques. Reflecting extensive
reader feedback, they have deepened and clarified coverage throughout, and
reorganized content for even greater ease of understanding. New and revamped
coverage in this edition includes

Better ways to start "thinking in patterns"

How design patterns can facilitate agile
development using eXtreme Programming and other methods
How to use commonality and variability
analysis to design application architectures
The key role of testing into a patterns-driven
development process
How to use factories to instantiate and manage
objects more effectively
The Object-Pool Pattern—a new pattern not
identified by the "Gang of Four"
New study/practice questions at the end of
every chapter
Gentle yet thorough, this book assumes no
patterns experience whatsoever. It's the ideal "first book" on patterns, and a
perfect complement to Gamma's classic Design Patterns. If you're a
programmer or architect who wants the clearest possible understanding of
design patterns—or if you've struggled to make them work for you—read this
book.
