{"product_id":"refactoring-improving-the-design-of-existing-code","title":"Refactoring: Improving the Design of Existing Code","description":"Refactoring is about improving the design of existing code. It is the process of changing a software system in such a way that it does not alter the external behavior of the code, yet improves its internal structure. With refactoring you can even take a bad design and rework it into a good one. This book offers a thorough discussion of the principles of refactoring, including where to spot opportunities for refactoring, and how to set up the required tests. There is also a catalog of more than 40 proven refactorings with details as to when and why to use the refactoring, step by step instructions for implementing it, and an example illustrating how it works The book is written using Java as its principle language, but the ideas are applicable to any OO language.\u003cbr\u003eASIN: 0201485672\u003cbr\u003eVSKU: 31UI56005S5B_ns\u003cbr\u003eCondition: Good\u003cbr\u003eAuthor\/Artist:Martin Fowler|Kent Beck|John Brant|William Opdyke|Don Roberts|Erich Gamma\u003cbr\u003eBinding: Hardcover\u003cbr\u003e\u003cb\u003eNote:\u003c\/b\u003e Any images shown are stock photographs and product may differ from what is shown.  \u003cbr\u003e\u003cb\u003eCondition Notes\u003c\/b\u003e: The item shows wear from consistent use, but it remains in good condition and works perfectly.
