Written by José Dimas Luján Castillo and Ron Veen - seasoned developers with deep expertise in Java and Kotlin - this practical guide teaches Kotlin through side-by-side Java comparisons, real-world examples, and clear explanations of modern language features.Key FeaturesLearn Kotlin by drawing direct comparisons to core Java conceptsUnderstand null safety, coroutines, extension functions, and DSLs through practical examplesUse Kotlin confidently in backend, Android, and cross-platform developmentPurchase of the print or Kindle book includes a free PDF eBookBook DescriptionThis book is a hands-on programming guide for Java developers who want to gain practical, production-ready knowledge of Kotlin. Whether you’re maintaining Java systems or adopting Kotlin for Android, backend, or cross-platform projects, it will help you bridge the gap by building on your existing understanding of Java’s syntax and design principles.You’ll begin by learning why Kotlin was created and how it improves on Java – exploring types, expressions, control flow, and null handling while mapping each concept to familiar Java constructs. Each topic is introduced with clear purpose, showing how Kotlin’s concise syntax, safety features, and expressive APIs lead to cleaner, more maintainable code.As you progress, you’ll master object-oriented and functional programming, extension functions, smart casting, and interoperability with Java. The second half of the book dives into generics, data and sealed classes, coroutines for concurrency, and DSL design – demonstrating when and why to use these features to build scalable, elegant solutions.By the end, you’ll not only write idiomatic Kotlin but also understand the reasoning behind its design, enabling you to craft modern, reliable applications with confidence.What you will learnWrite Kotlin programs using variables, functions, and control flowModel real-world data with classes, properties, and constructorsHandle missing data safely with nullable types and safe callsSimplify logic using lambdas and extension functionsWork with Kotlin collections and sequences to process data efficientlyUse Kotlin with Java, Gradle, and Maven for seamless project buildsWrite non-blocking code using coroutines and Async flowsCreate custom DSL for your projectsWho this book is forThis book is for software developers who are proficient in Java and want to learn Kotlin for professional application development. It’s especially relevant for Android engineers, JVM backend developers, and full-stack programmers who maintain or extend Java systems. Familiarity with core Java syntax and object-oriented programming is expected.

Discover the exciting new APIs introduced by Java’s Project Loom. This quick guide covers all the essential concepts the Java developer needs in order to understand virtual threads, structured concurrency, and scoped values.Authors Ron Veen and David Vlijmincx clearly explain the superiority of virtual threads, introduced in Java 21, over the traditional Java threads of the past 25 years. Then they dive into how structured concurrency streamlines interactions by treating related threads as a unified unit of work, akin to the impact of structured programming on regular programming. From there, the authors explore the third Project Loom API and scoped values, clarifying their advantages over regular ThreadLocals and providing efficient usage insights. The book concludes with an exploration of common scheduling strategies.By the end of this book, you will have a solid understanding of the concepts behind Project Loom and will be able to immediately apply this knowledge to your own code. You WillDiscover what virtual threads are, why they were created, and how to use them in your codeGain insight into how concurrency improves the observability of codeWrite your own StructuredTaskScopes tailored to your needsUnderstand why you should replace ThreadLocals with Scoped ValuesKnow the different strategies for multithreaded computer programs Who This Book is ForJava developers of any level. This knowledge is so fundamental to staying relevant in the Java job market that every developer needs to understand it for their career development.
