Master the concise and expressive power of a pragmatic multi-paradigm language for JVM, Android and beyond Key Features Language fundamentals Object-oriented and functional programming with Kotlin Kotlin standard library Building domain-specific languages Using Kotlin for Web development Kotlin for Android platform Coroutine-based concurrency Description The purpose of this book is to guide a reader through the capabilities of the Kotlin language and give examples of using it for development of various applications be it desktop, mobile or Web. Although our primary focus is on the JVM and Android, the knowledge we’re sharing here to various extents applies to other Kotlin-supported platforms such as JavaScript, native and even multi-platform applications. The book starts with an introduction to language and its ecosystem that will give you an understanding of the key ideas behind Kotlin design, introduce you to the Kotlin tooling and present you the basic language syntax and constructs. In the next chapters we’ll get to know the multi-paradigm nature of Kotlin which allows you to create powerful abstractions by combining various aspects of functional and object-oriented programming. We’ll talk about using common Kotlin APIs such as the standard library, reflection, and coroutine-based concurrency as well as the means for creating your own flexible APIs based on domain-specific languages. In the concluding chapters, we’ll give examples of using Kotlin for more specialized tasks such as testing, building Android applications, Web development and creating microservices.

We’ll talk about using common Kotlin APIs, such as the standard library, reflection, and coroutine-based concurrency as well as the means for creating your own flexible APIs based on domain-specific languages. What you will learn By the end of the book you’ll obtain a thorough knowledge of all the basic aspects of Kotlin programming. You’ll be able to create a flexible and reusable code by taking advantage of object-oriented and functional features, use Kotlin standard library, compose your own domain-specific languages, write asynchronous code using Kotlin coroutines library as well. You’ll also have a basic understanding of using Kotlin for writing test code, web applications and Android development. This knowledge will also give you a solid foundation for deeper learning of related development platforms, tools, and frameworks. Who this book is for The book is primarily aimed at developers who are familiar with Java and JVM and are willing to get a firm understanding of Kotlin while having little to no experience in that language. Discussion of various language features will be accompanied, if deemed necessary, by comparisons with their Java’s analogs, which should simplify the Java-to-Kotlin transition. Most of the material, however, is rather Java-agnostic and should be beneficial even without prior knowledge of Java. In general, experience in object-oriented or functional paradigm is a plus, but not required. Table of Contents 1. Kotlin: Powerful and Pragmatic 2. Language Fundamentals 3. Defining Functions 4.
