In this course, staff author Simon Allardice introduces the formalized, disciplined approach to refactoring that tells you exactly what to look for in your code, and how to fix it, through a series of "code smells"—clues that let you look at a block of code and realize when there's something wrong with it.

Topics include:

• What is refactoring?
• Recognizing common code smells
• Simplifying method calls
• Making conditions easier to read
• Using refactorings at the method, class, and application level
