![Kotlin In-Depth [Vol-I]](https://library.ardhindie.com/contents/assets/images/blank.png){kind=small}
Master the concise and expressive power of a pragmatic, multi-paradigm language for JVM, Android and beyond DESCRIPTIONÊ 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 weÕre 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. WeÕll 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 give examples of using Kotlin for more specialized tasks, such as testing, building Android applications, Web development and creating microservices. Ê KEY FEATURESÊ _Ê Language fundamentals _Ê Object-oriented and functional programming with Kotlin _Ê Kotlin standard library _Ê Building domain-specific languages _Ê Using Kotlin for Web development _Ê Kotlin for Android platform _Ê Coroutine-based concurrency Ê WHAT WILL YOU LEARNÊ By the end of the book youÕll obtain a thorough knowledge of all the basic aspects of Kotlin programming. YouÕll 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. YouÕll 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. Ê WHO IS THIS BOOK FORÊ 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 JavaÕs 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. Ê Table of Contents 1. Ê Ê Kotlin: Powerful and Pragmatic 2. Language Fundamentals 3.

Kotlin In-Depth
It's easy to learn, so you can start making powerful apps right away. KEY FEATURES ● Numerous code samples covering all aspects of the Kotlin language. ● Coverage on native applications, web apps, microservices, and app testing. ● Step-by-step instructions are provided in a clear and concise manner. DESCRIPTION The book ‘Kotlin In-Depth, Second Edition’ updates all the essential parts of Kotlin and incorporates modern principles, methodologies, and approaches for achieving efficient solutions. The book will guide you to successfully utilize Kotlin in developing JVM apps for desktop, mobile, web platforms and transferring existing Java codebases to Kotlin. The book begins with an introduction to the language and its environment, which will help you to grasp the fundamental concepts underlying Kotlin's design. The readers will learn the Kotlin tooling and the language's core syntax and structures. The book teaches Kotlin's multi-paradigm nature, which enables the creation of powerful abstractions by mixing parts of functional and object-oriented programming. This book discusses how to use standard Kotlin APIs like the standard library, reflection, and coroutine-based concurrency, as well as how to create your flexible APIs using domain-specific languages. The book demonstrates how to use Kotlin for more specific tasks such as testing, developing Android applications, developing Web applications, and developing microservices. After reading this book, you'll be prepared to dive deeper into the Kotlin ecosystem's more specialized areas, including Android applications, server-side development, native programming, and code sharing across different platforms. WHAT YOU WILL LEARN ● Acquire a deep understanding of all fundamental features of Kotlin programming. ● Utilize object-oriented and functional capabilities to create a flexible and reusable codebase. ● Leverage the Kotlin standard library to create custom domain-specific languages. ● Implement the Kotlin coroutines package to write asynchronous programming. ● A solid foundation of relevant development platforms, tools, and frameworks. WHO THIS BOOK IS FOR The book is primarily geared towards Java and JVM developers who want to learn Kotlin and explore modern and efficient development techniques. Knowing the basics of programming is helpful but not necessary. TABLE OF CONTENTS 1. Kotlin - Powerful and Pragmatic 2. Language Fundamentals 3. Defining Functions 4.
