Summary Kotlin in Action guides experienced Java developers from the language basics of Kotlin all the way through building applications to run on the JVM and Android devices. Foreword by Andrey Breslav, Lead Designer of Kotlin. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology Developers want to get work done - and the less hassle, the better. Coding with Kotlin means less hassle. The Kotlin programming language offers an expressive syntax, a strong intuitive type system, and great tooling support along with seamless interoperability with existing Java code, libraries, and frameworks. Kotlin can be compiled to Java bytecode, so you can use it everywhere Java is used, including Android. And with an effi cient compiler and a small standard library, Kotlin imposes virtually no runtime overhead. About the Book Kotlin in Action teaches you to use the Kotlin language for production-quality applications. Written for experienced Java developers, this example-rich book goes further than most language books, covering interesting topics like building DSLs with natural language syntax. The authors are core Kotlin developers, so you can trust that even the gnarly details are dead accurate. What's Inside Functional programming on the JVM Writing clean and idiomatic code Combining Kotlin and Java Domain-specific languages About the Reader This book is for experienced Java developers. About the Author Dmitry Jemerov and Svetlana Isakova are core Kotlin developers at JetBrains. Table of Contents PART 1 - INTRODUCING KOTLIN Kotlin: what and why Kotlin basics Defining and calling functions Classes, objects, and interfaces Programming with lambdas The Kotlin type system PART 2 - EMBRACING KOTLIN Operator overloading and other conventions Higher-order functions: lambdas as parameters and return values Generics Annotations and reflection DSL construction

Kotlin is a free and open-source general-purpose programming language that is mostly used to create Android apps. It was developed by JetBrains initially and later on picked up by Google as language of chioice for its Android platform. Over the past few years, Kotlin has become one of the most popular programming languages over Java Language and is used by more than 80% of Android apps developers. Kotlin is a statically typed, advanced programming language that compiles Kotlin code into Java byte-code and runs on a Java Virtual Machine (JVM). It can also be compiled to native executables and JavaScript source code. It is an object-oriented programming language that includes data types, operators, I/O comments, control statements, functions, classes, object expressions, and constructors, among other features. It is not a standalone programming language; rather, is an innovative manner of coding that runs on Java. Kotlin is a versatile language with some interesting and cool features like compatibility, low runtime, and efficient coding characteristics. The features that help Kotlin distinguish out from other languages are its reliability, tool support, and interoperability. It is a simplified version of Java that is much easier to deal with. Why Should You Learn Kotlin? The popularity of Kotlin is growing, and it will continue to do so in the coming years. Kotlin has always been, and will continue to be, a cutting-edge programming language that best meets the needs of real professionals. Many emerging fields, including mobile, online gaming, server-side, and cloud development, data science, and education, are progressively using Kotlin. All of this indicates that there is already a high demand for Kotlin developers, and that demand will continue to grow in the future. Furthermore, if you are looking to build native Android apps, Kotlin is the language that you should be using. In This Book Step by step approach to problem solving and skill development A quick run-through of the basic concepts, in the form of a "Crash Course" Advanced, hands-on core concepts, with a focus on real-world problems Industry level coding paradigm, practice-oriented explanatory approach Special emphasis on writing clean and optimized code, with additional chapters focused on coding methodology

Write More Robust and Maintainable Android Apps with Kotlin “Peter Sommerhoff takes a practical approach to teaching Kotlin by providing a larger set of code listings that demonstrate language features and by guiding readers through the development of two Android apps step by step. . . . Peter finds a good balance between what is essential and what can be left to readers, so this book is an efficient yet comprehensible source for starting programming with Kotlin.” –Bernhard Rumpe, Professor of Software Engineering, RWTH Aachen University The Kotlin language brings state-of-the-art programming techniques and constructs to Android development. Kotlin for Android App Development will help you rapidly understand Kotlin’s principles and techniques, apply Kotlin in production app development, integrate Kotlin with existing Java code, and plan a migration to Kotlin, if you choose. If you have at least basic programming experience (with any language), Peter Sommerhoff’s well-crafted overview and examples will help you get quickly up-to-speed with the Kotlin language, its constructs, and its advanced functional and object-oriented capabilities. Once you’ve mastered these foundations, Sommerhoff walks you through two complete app development projects, introducing best practices and emerging patterns for writing code that’s robust, concise, readable, and highly performant. Understand Kotlin’s goals, principles, advantages, design, and constructs Take full advantage of functional programming in the Kotlin environment Write more concise and reusable code using Kotlin’s object-oriented features Interoperate with existing Java code, and plan a migration to Kotlin Use coroutines to efficiently handle concurrency Capture data via third-party APIs, map it to internal data representations, and present it to users Master best practices for architecting Kotlin Android apps Improve productivity and readability by creating simple domain-specific languages in Kotlin
