Miroslav Wengner is a Java Champion and JavaOne Rockstar with an impressive career. I had courses on design patterns in university, but I wished I had this book then to guide me through these topics. These chapters feel like an encyclopedia, which I'll probably revisit occasionally whenever I need to do a more complex architecture. They give a (slightly opinionated) view of all the major design patterns, complete with small examples and examples from the JDK. The chapters on design patterns are also significant. The author did an excellent job introducing the Java Runtime Environment, with many pointers to other superior reading materials. It gives you a great introduction to modern Java features and common pitfalls this book is valuable even if you are not interested in design patterns. But I was wrong this book gives you far more than a short descriptive compilation of design patterns. When I first read the book's title, I thought, "another book on the good old design patterns," and wondered why I should bother reading it. When someone starts a programming career with Java and has a solid understanding of design patterns, many bad practices can be avoided. Only when you learn and understand patterns and debugging and use a strongly typed language like Java do you start writing "real" code. When you start using a programming language like Python, JavaScript, or even Java, the platform allows you to create messy code. The book's goal is to break a returning pattern many programmers go through during their careers. On top of that, this book also provides a lot of extra information related to the recent changes in the OpenJDK, which brought a lot of evolutions into the Java programming language and made it once more the preferred language for many different use cases. The book by Miroslav Wengner is precisely the kind of book I was missing when I got more experienced in Java development and wanted to uplift my career. It was only by following courses and, most importantly, learning from colleagues that I started making "readable and maintainable" code, which is precisely the topic of this book.Īfter many years of being the only Java developer in a team of hardware and embedded engineers, I was introduced to SOLID and other principles when more Java colleagues joined and helped me to turn my "ugly" code to clean and structured projects. I've been programming since I was 10y old, but I graduated from film school as a video editor, so I never learned the "official" way to be a programmer. We'll start this post with the personal verdict of two avid readers of this book: Frank Delporte's Verdict This book is for sale on Amazon in Kindle and Paperback editions.
