Summary:

Now you can dramatically improve the design, performance, and manageability of object-oriented code without altering its interfaces or behavior. Refactoring shows you exactly how to spot the best opportunities for refactoring and exactly how to do it-step by step. Through more than forty detailed case studies, you'll learn powerful - and surprisingly simple - ways to redesign code that is already in production. You'll learn scores of specific techniques, including when to move fields between classes, when to move code up or down its hierarchy, and when to divide a single method into two. Through intuition and trial and error, master programmers have spent years evolving these techniques; this book brings them all together into a comprehensive guide that any experienced developer can use.
