This 25-year-old classic describes the most relevant design patterns in great detail, though its academic style makes it challenging to read. Despite outdated code examples and no coverage of modern aspects like concurrency, every programmer should know and apply these 23 classic patterns. For those seeking a more practical approach, Dr. Heinz Kabutz's online course is recommended.
In "The Programmer's Brain," Professor Felienne Hermans explains how our brain functions during programming tasks, exploring memory systems and cognitive processes like chunking. The book reveals why we experience cognitive overload with unfamiliar code and offers science-backed techniques to reduce it. With accessible language and practical examples, it helps programmers understand why clean code practices are effective and how to better manage complex challenges.
Though published in 1999, Doug Lea's comprehensive guide to Java concurrency remains highly relevant today. The book covers essential principles and patterns that are foundational to thread-safe programming. While the academic writing style presents a challenging read requiring patience and concentration, mastering these concepts will significantly improve your coding skills, making you a sought-after Java programmer.
This approachable book by one of the original "Design Patterns" authors offers practical insights into the development process and clarifies common misunderstandings about patterns. It presents familiar patterns through real-world examples – a refreshing contrast to the academic style of the classic – along with pattern variations and two new designs. A pleasant, digestible companion to the original that enriches your pattern knowledge.
"Java Concurrency in Practice" by Brian Goetz and the JSR 166 expert team tackles the challenge of writing thread-safe applications with multi-core CPUs. The book covers fundamentals of concurrency from basics to advanced topics, with excellent real-world examples. Though complex, it explains the Java Memory Model exceptionally well and remains relevant despite being written for Java 6.
This book on Java Generics and Collections quickly moves beyond basics to address advanced topics like Wildcards and Bounds that many developers struggle with. The second part thoroughly examines the Java Collection Framework, comparing implementations for concurrency and performance. You'll find clear explanations for concepts that most programmers encounter but rarely fully understand – making it essential reading for any advanced Java developer seeking to strengthen their fundamental knowledge.
Mastering Lambdas offers excellent coverage of Java 8's features, with Lambdas comprising just the first quarter while Streams take center stage. You'll find this book valuable regardless of your expertise level – beginners will appreciate the step-by-step approach to Lambdas and Streams, while advanced developers will discover how to create custom Spliterators, Collectors, and Reducers for more sophisticated applications.
As the standard reference for Java programmers for 25 years, 'Core Java: Fundamentals' has been completely revised by Java Champion Cay S. Horstmann for Java 21. Volume I offers a comprehensive journey from basic programming concepts to advanced features like virtual threads, pattern matching, and sealed classes – making it essential for both beginners and experienced developers.
Core Java: Advanced Features (Volume 2) offers experienced Java programmers in-depth coverage of advanced topics like streams, I/O, database programming, XML processing, and UI development. Both volumes provide comprehensive, well-structured content with hundreds of practical code examples updated with modern language features. The books balance technical depth with readability, making them an excellent resource for Java programmers at all experience levels.
Uncle Bob's 'Clean Architecture' presents a software architecture approach where domain components are separated from technical implementation details, with dependencies flowing inward. The book covers design principles, practical examples, and entertaining industry anecdotes from the author's career. It demonstrates how proper architecture allows software to adapt to changing requirements with minimal effort – essential knowledge for all software architects and programmers.
In this excellent book, "Uncle Bob" Martin explains core concepts of agile software development, Extreme Programming, and Test-First Design. He demonstrates how to write clean code through SOLID principles and design patterns, illustrated with three practical case studies in C++ and Java. Although from 2002, this highly recommended book offers valuable insights every programmer should study intensively.
This book presents concentrated, practical programming knowledge with best practices and pitfalls from decades of experience. It focuses on creating high-quality, flexible, and maintainable code. Valuable for both beginners and experienced programmers, it offers structured knowledge that would otherwise take years to develop. With anecdotes, analogies, and practical exercises, it's an essential read that balances expertise with accessibility.
This practical guide to Test-Driven Development demonstrates how unit tests and mock objects create clean object-oriented designs with maintainable code. The authors, including jMock's developer, walk you through implementing a Java auction system using TDD principles. Especially valuable for Java programmers, this book shows how tests naturally lead to more elegant designs – once you experience this approach, you'll never want to develop without it.
This classic book teaches developers how to write code that's not just functional but easily readable and maintainable. It covers essential principles like meaningful naming, concise functions, and proper error handling through entertaining Java examples. Every developer should internalize these practices, though the concurrency chapter oversimplifies complex issues. The review recommends supplementing with "Java Concurrency in Practice" and adopting established code style guides rather than creating your own.
Martin Fowler's classic book introduces refactoring and code smells to the broader developer community. The extensively updated second edition features a catalog of over 60 refactorings, illustrated with JavaScript examples instead of Java. While not light reading, it's a timeless must-read for all developers – offering beginners an excellent introduction and teaching professionals new techniques or formalizing their intuitive practices.
In "Clean Craftsmanship," Uncle Bob Martin presents essential software development practices every professional should master. The book covers disciplines like TDD (which takes up nearly half the content), refactoring, and pair programming; standards for balancing productivity with quality; and ethical responsibilities to users, colleagues, and society. Like all of Martin's works, it's accessible, enriched with historical context and personal anecdotes, and highly recommended for developers.
This book offers strategies for working with legacy code – systems without tests – by breaking dependencies to create testable code modules. Though 15 years old, with some outdated practices regarding interfaces, factory methods, and no coverage of multithreading, it remains valuable for programmers facing untested codebases. The formalized strategies and naming conventions improve team communication, but remember: there's an exception to every rule!
Joshua Bloch's "Effective Java" presents 90 essential best practices for writing efficient, readable, and maintainable Java code. Aimed at experienced programmers, this comprehensive guide offers specific advice with clear code examples across 11 topics. While some practices may be familiar, others will elevate your skills. Every Java developer should read it entirely, then reference specific articles as needed. Ensure you get the current third edition.
In this entertaining book, Java platform co-developers Bloch and Gafter present 95 puzzling Java programs that reveal unexpected behaviors, pitfalls, and corner cases. Every puzzle is instructive, with detailed explanations and humorous commentary. While some examples are contrived, many address common issues you'll encounter regularly. Despite being limited to Java 5, the book offers valuable insights for developers seeking to write more robust code.
In 'Implementing Domain-Driven Design,' Vaughn Vernon guides readers through DDD implementation with a fictional team, covering both strategic and tactical design alongside compatible architectures. The book demonstrates how mistakes and learning make DDD's initial effort worthwhile. With practical Java examples, it serves as an excellent companion to Evans' classic but stands on its own. Recommended for anyone wanting to successfully apply Domain-Driven Design in practice.
