Textbook in PDF format A concise handbook for the most common tools used in modern Java development. Good Java developers learn Java syntax, how to create loops and switches, and can work out a lambda filter stream. But great Java developers need to understand the vast ecosystem of tools and frameworks for collaboration, testing, building, and more. In Real-World Java: Helping You Navigate the Java Ecosystem, a team of veteran Java developers delivers a concise and authoritative discussion of the most common frameworks, tools, and techniques used in enterprise Java development shops. The authors provide just enough background and examples to allow you to dive right into the expert guidance on annotations, logging frameworks, observability, performance tuning, testing tools, and collaboration, that real-life commercial Java development typically relies on. You’ll expand your Java development toolkit with frameworks and utilities like Spring, Git, Prometheus, and Project Lombok. You’ll also discover links to tested, downloadable code examples that demonstrate the skills discussed in the book. You've journeyed through loops, switches, and exception handling, you've made sense of lambdas and streams, and you're starting to get comfortable with the core Java APIs. You've built a solid foundation, and that's no small accomplishment—You are ready to start your elite career as a Java engineer! But Java is more than a language; it's a vast ecosystem filled with tools, platforms, libraries, and APIs that empower you to extend Java's capabilities into every corner of enterprise development. This book is your guide to navigating that ecosystem. While numerous tomes delve into specialized areas of Java, few provide an accessible roadmap across the broader landscape. Here, you'll find clear explanations and practical coding examples of the technologies you can expect to encounter most often in enterprise Java environments. The knowledge you gain here will prepare you to delve deeper into additional resources and broaden your skills in this dynamic ecosystem. Real-World Java is the perfect resource for everyone already somewhat comfortable with the language but who wants to familiarize themselves with the tools and frameworks used in contemporary Java software development
