From the Back Cover

Praise for Design Patterns Java(TM) Workbook

"An excellent book... I'm incredibly impressed with how readable it is. I understood every single chapter, and I think any reader with any Java familiarity would. This book is going to be required reading in a lot of places, including my office."

--Joshua Engel

"Provides a new, more Java-literate way to understand the 23 GoF patterns."

--Bob Hanmer

"This book translates Design Patterns into what Java programmers need to know. It is full of short, engaging programming and design problems with solutions--making it easy for programmers to work through solutions and really make patterns 'stick.'"

--Rebecca Wirfs-Brock

"This is one exciting book. It's approachable, readable, interesting, instructive, and just plain valuable. It'll eclipse all other books purporting to teach people the GoF patterns in Java--and perhaps any other language."

--John Vlissides

Java programmers, you now have the resource you need to harness the considerable power of design patterns. This unique book presents examples, exercises, and challenges that will help you apply design pattern theory to real-world problems. Steve Metsker's learn-by-doing approach helps you enhance your practical skills and build the confidence you need to use design patterns effectively in mission-critical applications.

Design Patterns Java(TM) Workbook features the twenty-three foundational design patterns introduced in the classic book Design Patterns (Addison-Wesley, 1995). In this new, hands-on workbook, the patterns are organized into five major categories: interfaces, responsibility, construction, operations, and extensions. Each category begins with a chapter that reviews and challenges your ability to apply facilities built into Java. These introductory sections are followed by chapters that explain a particular pattern in detail, demonstrate the pattern in use with UML diagrams and Java code, and provide programming problems for you to solve.

With this book you will build expertise in important areas such as:

• Adapting domain data to Swing components
• Creating a FACADE for Swing
• Handling recursion in composites
• Understanding the role of BRIDGE in Java database connectivity
• Making the connection between Model/View/Controller and OBSERVER
• Maintaining relational integrity with a mediator
• Using proxies to communicate between computers
• Letting a service provider decide which class to instantiate
• Supporting undo operations with MEMENTO
• Prototyping with clones
• Using COMMAND to supply a service
• Developing thread-safe iterators
• Extending classes with DECORATOR and VISITOR

Solutions to the design pattern challenges appear in the back of the book, so you can compare your own work to expert approaches. A brief guide to UML explains the modeling notation, and an accompanying Web site provides all the code examples from the book.

Through the instruction and exercises offered in Design Patterns Java(TM) Workbook , you can fully understand the role of design patterns in Java application development, and enhance your ability to put design patterns to work.

At OOPSLA 2000 in Minneapolis, Minnesota, I asked Mike Hendrickson of Addison-Wesley what types of books he thought readers wanted. I was interested to hear that he felt that there is still a market for books to help readers understand design patterns. I suggested the idea of a Java workbook that would give readers a chance to expand and to exercise their understanding of patterns. This sounded good to Mike, and he introduced me to Paul Becker, who supports Addison-Wesley's Software Patterns series. Paul's immediate response was that such a book "should have been written five years ago." I would like to thank Mike and Paul for their initial encouragement, which inspired me to take on this task.

Since that initial meeting, Paul has supported me throughout the entire development process, guiding this book toward publication. Early on, Paul asked John Vlissides, the Software Patterns series editor, for his views on the project. John's reply was that Paul should support the project "in all wise," inspirational words that have stayed with me throughout.

John Vlissides is also, of course, one of the four authors of Design Patterns. John and his coauthors--Erich Gamma, Ralph Johnson, and Richard Helm--produced the work that is in every way the foundation of this book. I referred to Design Patterns nearly every day that I worked on this book and can hardly overstate my reliance on it.

I have also relied on many other existing books, which are listed in the bibliography at the end of this book. In particular, I have depended on The Unified Modeling Language User Guide (Booch, Rumbaugh, and Jacobson 1999) for its clear explanations of UML. For accuracy in Java-related topics I have consulted Java™ in a Nutshell (Flanagan 1999b) almost daily. I have also repeatedly drawn on the insights in Patterns in Java™ (Grand 1998) and Java™ Design Patterns (Cooper 2000).

During the months that I was working on this book, I also worked at a financial services institution that has facilities in many locations. As the book emerged, I developed an instructor's course to go with it. I taught the course in Richmond, Virginia, and my associates Tim Snyder and Bill Trudell taught the course concurrently at other locations. I would like to thank these instructors and the students from all three courses for their inspiration and their many insights. In particular, I would like to thank Srinivasarao Katepalli, Brad Hughes, Thiaga Manian, Randy Fields, Macon Pegram, Joe Paulchell, Ron DiFrango, Ritch Linklater, Patti Richards, and Ben Lewis for their help and suggestions. I would also like to thank my friends Bill Wake and Gagan Kanjlia for their reviews of this book in its early stages and Kiran Raghunathan for his help in the later stages. Finally, I'd like to thank my friend Jeff Damukaitis for his suggestions, particularly his insistence that I make the code for this book available to readers. (It is, at oozinoz).

As the book came along, Paul Becker arranged for many excellent reviewers to help guide its progress. I'd like to thank John Vlissides again for his reviews. In every review, John somehow convinced me that he liked the book while simultaneously pointing out scores of significant improvements. I'd like to thank Luke Hohmann, Bob Hanmer, Robert Martin, and Joshua Kerievsky for their help at various stages. Each of them made this book better. I'd like to thank Joshua Engel, who has an amazing ability to blend sharp insight with a gentle touch. Finally, I'd like to thank Rebecca Wirfs-Brock, who had many great suggestions, including completely reorganizing the book. I had initially not taken care to put important but understandable patterns up front. The book is much stronger now because of Rebecca's advice and the help of all the book's reviewers.
