Kotlin In

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

The purpose of this book is to guide a reader through the capabilities of Kotlin language and give examples of how to use it for the development of various applications, be it desktop, mobile or Web. Although our primary focus is on JVM and Android, the knowledge were 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 the language and its ecosystem, which will give you an understanding of the key ideas behind the Kotlin design, introduce you to the Kotlin tooling and present you the basic language syntax and constructs. In the next chapters, we get to know the multi-paradigm nature of Kotlin which allows us to create powerful abstractions by combining various aspects of functional and object-oriented programming. Well 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 will you learn
By the end of the book youll obtain a thorough knowledge of all the basic aspects of Kotlin programming. Youll 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. Youll 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 Javas 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.
