Please bear in mind that we do not own copyrights to these books. These are not conflicting goals: error handling can be seen as a separate concern, independent of the main logic. Error handling is one of those areas that is seldom done well, and is usually skirted around in literature about software design. Which door reflects your staff or your business? All they can do is give you some of the tools, techniques, and thought processes that other artists have used. In other words, talk to friends, not to strangers.
With all of that said, I'd definitely recommend the book to Java developers at the beginner and intermediate levels. The next portion of the publication is that the harder work. Make your code as easy as possible to understand. Code cleanliness is an area where the core of just-plain-good ideas is surrounded by a nimbus of sometimes contradictory standards that people pick and choose from. You'll be reading code--lots of code.
The Case Studies In chapters 14, 15, and 16, Martin ties the ideas from the previous chapters together. When you write a paper or an article, you get your thoughts down first, then you massage it until it reads well. Using inconsistent spellings is disinformation. Boolean arguments loudly declare that the function does more than one thing. Three arguments triadic should be avoided where possible. Martin series, you might skip this one.
Or if you have the c This book is repetitive at times and mentions content already covered in some of the other books in the Robert C. It doesn't go into great depth, and feels a little bolted-on, but does contain a good deal of solid advice. You can discover the range of books from here. Martin makes use of extensive examples and case studies to hone our ability to identifying code that has room for improvement, and provides a multitude of techniques to clean up code, just a little, every time we touch it. Martin does a reasonably good job of taking code that may seem reasonable on the surface and improving its readabilty.
The next person to touch this code will certainly be happy to deal with cleaner code! No longer likely to be applicable. Classes belong to higher levels of code organization. The examples could be useful for someone who isn't in a code-review-heavy environment. And you will be challenged to think about what s right about that code, and what s wrong with it. Having reignited my love of programming I have dived into learning Unity with an aim to build games. But the really irritating references were to Martin's previous book, Principles, Patterns, and Practices. More importantly, you will be challenged to reassess your professional values and your commitment to your craft.
The second rule of functions is that they should be smaller than that. Mình khuyên các bạn nên mua bản gốc, 1 là để đọc, 2 là nếu gặp thằng nào code ngu, có thể cầm cuốn này đập vào đầu nó và bắt nó đọc. But it doesn t have to be that way. That said, his comments indicate that he often has a higher opinion of the cleanliness of his end result than I do. Clean code always looks like it was written by someone who cares.
The people who read your code will be programmers so if there is a commonly understood term, it's ok to use it. Its simple, clean, and well crafted. But it doesn t have to be that way. It condenses the ideas of the book into a very direct, problem-centric format, ideal for review. Stepdown rule: every function should be followed by those at the next level of abstraction low, intermediate, advanced. Cứ tưởng tượng thằng developer bảo trì code của bạn mà đọc những dòng code bạn viết …. The proper use of comments is to compensate for our failure to express ourself in code.
Chapter 9 covers Unit Tests: why keeping them clean is as important as keeping your production code clean, and how to keep your tests clean. The result is a knowledge base that describes the way we think when we write, read, and clean code. The latter section of the book contains some worked examples that I didn't always agree with because they seemed to be totally over done. The first half of this book is well worth a read. This is where everything you've read so far will really begin to sink in and acquire practical relevance.
