Kotlin for Java Developers: Confidently transition from Java to Kotlin through hands-on examples and idiomatic Kotlin practices

Synopsis

Written by José Dimas Luján 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 designed for developers who are fluent in Java and want to gain working knowledge of Kotlin. Whether you're maintaining Java systems or adopting Kotlin for Android, backend, or cross-platform development, this book teaches Kotlin in a way that leverages your existing understanding of Java's syntax and structure. The book opens with the basics of Kotlin types, expressions, and control flow—mapping each feature to its Java counterpart to build fluency quickly. You'll then explore object-oriented and functional programming constructs, understand how Kotlin improves null handling, and learn when and how to apply Kotlin's concise features like extension functions, coroutines, DSLs, and smart casting. You’ll also learn how Kotlin interoperates with Java, configure Kotlin in Maven and Gradle projects, and use modern Kotlin tooling. Later chapters cover Kotlin's use in backend and cross-platform applications, giving you a rounded understanding of how and where to apply the language effectively. By the end of the book, you’ll be able to read and write idiomatic Kotlin, refactor Java code, and structure Kotlin projects 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.
