This book gives many examples which help you to write clean code. For more information like principles, patterns, techniques, and tools have a look at my book Clean Code Fundamentals. Nothing affects the work of a team as much as bad, illegible, sloppy, and quickly written code that has not been designed carefully. Team dynamics can be improved, requirements can be redefined, and the schedule can be modified. However, if bad code takes over, it becomes more and more a burden for the team. Programmers should develop all the time. Even if they think that they have sufficient skills and knowledge to move around in current projects, they should not stop there, and it is worthwhile for them to learn new concepts, approaches, language, and frameworks from time to time. Learning should be a journey and not a destination. This book discusses the best practices of writing better code. It also contains many code examples in Java of increasing complexity. The book will use the latest Java version for the examples provided.
