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 Features

Learn Kotlin by drawing direct comparisons to core Java concepts
Understand null safety, coroutines, extension functions, and DSLs through practical examples
Use Kotlin confidently in backend, Android, and cross-platform development
Purchase of the print or Kindle book includes a free PDF eBook

Book Description

This book is a hands-on programming guide designed for developers who are fluent in Java and want to gain working knowledge of Kotlin. Whether youre 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 Javas syntax and structure. The book opens with the basics of Kotlin types, expressions, and control flowmapping each feature to its Java counterpart to build fluency quickly. Youll then explore object-oriented and functional programming constructs, understand how Kotlin improves null handling, and learn when and how to apply Kotlins concise features like extension functions, coroutines, DSLs, and smart casting. Youll also learn how Kotlin interoperates with Java, configure Kotlin in Maven and Gradle projects, and use modern Kotlin tooling. Later chapters cover Kotlins 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, youll be able to read and write idiomatic Kotlin, refactor Java code, and structure Kotlin projects with confidence.

What you will learn

Write Kotlin programs using variables, functions, and control flow
Model real-world data with classes, properties, and constructors
Handle missing data safely with nullable types and safe calls
Simplify logic using lambdas and extension functions
Work with Kotlin collections and sequences to process data efficiently
Use Kotlin with Java, Gradle, and Maven for seamless project builds
Write non-blocking code using coroutines and Async flows
Create custom DSL for your projects

Who this book is for

This book is for software developers who are proficient in Java and want to learn Kotlin for professional application development. Its 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.

Book Description

This 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.
