Download this PDF Book: Kotlin Cookbook: A Problem-Focused Approach 1st Edition by Ken Kousen
Welcome to Kotlin Cookbook! The overall focus of the book is not only to teach Kotlinsyntax and semantics, but also to show you when and why a particular feature shouldbe used.
The goal isn’t necessarily to cover every detail of Kotlin’s syntax and libraries.In the end, however, many recipes on basic principles were added to make the book understandable even to readers with only a beginning level of Kotlin knowledge.
There is a strong movement by Jet Brains to encourage the Kotlin community to embrace multiplatform, native, and JavaScript development. In the end, the decision was made not to include recipes involving them, since all are either in beta form or have very low adoption rates. As a result, the book concentrates exclusively on Kotlin for the JVM.
Use Kotlin to build Android apps, web applications, and more―while you learn the nuances of this popular language. With this unique cookbook, developers will learn how to apply this Java-based language to their own projects.
Both experienced programmers and those new to Kotlin will benefit from the practical recipes in this book.
Author Ken Kousen (Modern Java Recipes) shows you how to solve problems with Kotlin by concentrating on your own use cases rather than on basic syntax. You provide the context and this book supplies the answers.
Already big in Android development, Kotlin can be used anywhere Java is applied, as well as for iOS development, native applications, JavaScript generation, and more. Jump in and build meaningful projects with Kotlin today.
Apply functional programming concepts, including lambdas, sequences, and concurrency
See how to use delegates, late initialization, and scope functions
Explore Java interoperability and access Java libraries using Kotlin
Add your own extension functions
Use helpful libraries such as JUnit 5
Get practical advice for working with specific frameworks, like Android and Spring
Who Should Read This Book
This book is written for developers who already know the basics of object-oriented programming, especially in Java or another JVM-based language. While Java knowl‐edge would be helpful, it isn’t required.
A recipe book like this one is more focused on using the techniques and idioms of Kotlin than on being an exhaustive resource on the language.
That has the advantage of using the full power of the language in any given recipe, but the disadvantage ofspending only a limited time on the basics of those features. Each chapter includes asummary of the basic techniques, so if you are only vaguely familiar with how to cre‐ate collections, work with arrays, or design classes, you should still be fine.
The onlinereference manual provides a solid introduction to the language, and the book makesfrequent reference to examples and discussions found there.
In addition, the book frequently dives into the implementations of features from theKotlin libraries. That’s to show how the developers of the language work with it inpractice, as well as to discuss why things are done the way they are.
No prior knowl‐edge of the implementation is expected, however, and you are free to skip thosedetails if you are in a hurry
