Get the steps you need to discover the world of Java 9 programming using real-world examplesAbout This BookWe bridge the gap between “learning” and “doing” by providing real-world examples that will improve your software developmentOur example-based approach will get you started quickly with software programming, get you up-to-speed with Java 9, and improve your Java skillsThis book will show you the best practices of Java coding and improve your productivityWho This Book Is For

This book is for anyone who wants to learn the Java programming language. You are expected to have some prior programming experience with another language, such as JavaScript or Python, but no knowledge of earlier versions of Java is assumed.

What You Will LearnCompile, package and run a trivial program using a build management toolGet to know the principles of test-driven development and dependency managementSeparate the wiring of multiple modules from the application logic into an application using dependency injectionBenchmark Java execution using Java 9 microbenchmarkingSee the workings of the Spring framework and use Java annotations for the configurationMaster the scripting API built into the Java language and use the built-in JavaScript interpreterUnderstand static versus dynamic implementation of code and high-order reactive programming in JavaIn Detail

This book gets you started with essential software development easily and quickly, guiding you through Java's different facets. By adopting this approach, you can bridge the gap between learning and doing immediately. You will learn the new features of Java 9 quickly and experience a simple and powerful approach to software development. You will be able to use the Java runtime tools, understand the Java environment, and create Java programs.

We then cover more simple examples to build your foundation before diving to some complex data structure problems that will solidify your Java 9 skills. With a special focus on modularity and HTTP 2.0, this book will guide you to get employed as a top notch Java developer.

By the end of the book, you will have a firm foundation to continue your journey towards becoming a professional Java developer.

Style and approach
