Refactoring has gained widespread acceptance in the software engineering community as a proven means of improving software. Martin Fowler's seminal book on this topic, Refactoring, 0201485672, has been used in the classroom to explain that existing code could be improved and enhanced without significantly altering the fundamental structure of an application. But many find that this concept has a steep learning curve that inhibits its use. In this new book, William Wake offers a more introductory look at this important topic. The author outlines a proven workbook approach to learning and applying refactoring to “everyday” projects. This approach relies on examples that force the student to apply the main concepts of refactoring. As a result, readers gain thorough knowledge of how refactoring can help improve their software.

As a programmer, you need to be able to recognize and improve problematic code, so the program remains in a working state throughout the software lifecycle. Refactoring-the art of improving the design of existing code safely-provides an efficient, reliable system for bringing order to the chaos, and one that keeps the surprises to a minimum! Refactoring can be difficult to learn, but Refactoring Workbook, by consultant William C. Wake, presents the material in a easy-learning format that makes learning enjoyable and effective.
For many, the obstacle to learning refactoring is in identifying the 'smells'—the potential problem areas-found in code. Instead of having you read about the smells, Refactoring Workbook makes sure you understand them. You'll solve a carefully assembled series of problems, and you'll find yourself learning at a deeper level and arriving at a few insights of your own. Wake uses the workbook method—a learning-focused approach that forces you to apply the techniques presented in the book-in the rest of the book. This approach helps you learn and apply the most important refactoring techniques to your code and, as a side benefit, helps you to think more about creating great code even when you're not refactoring.

This book is intended for programmers with a knowledge of Java, though a C# or C++ programmer with a basic understanding of Java would also be able to follow and learn from the examples. It can be used as a companion to Martin Fowler's Refactoring (also from Addison-Wesley Professional), which provides step-by-step instructions for many refactorings.
WILLIAM C. WAKE is an independent software consultant, coach, and trainer who has been programming for over 20 years. He has previously worked for Capital One Financial, MCI/WorldCom, VTLS, Inc, and others. He is the author of Extreme Programming Explored, also available from Addison-Wesley Professional.
