Principles, Policies, and Applications of Kotlin Programming

Kotlin programming has been recognized as the main language for deploying Android projects, so this language has tremendous potential. In order to understand the main principles and best applications of Kotlin programming, further research is needed. Principles, Policies, and Applications of Kotlin Programming provides complete knowledge of Kotlin programming. It presents the latest technology of Vert.X, Restful API programming application by Kotlin, as well as authentication techniques for Restful APIs, which are new and important content in backend deployment for software. Covering topics such as array processing, graphic user interface, and string processing, this premier reference source is a valuable resource for software developers, programmers, students and educators of higher education, researchers, and academicians.
Kotlin Standard Library Cookbook

Publisher: Packt Publishing Ltd
Release Date: 2018-07-30
Build optimized applications in Kotlin by learning how to make use of the standard library features the smart way Key Features Get the most out of the Kotlin library to develop high-quality portable applications Explore the powerful support for data processing and I/O operations Discover ways to enhance your Android application development Book Description Given the verbosity of Java, developers have turned to Kotlin for effective software development. The Kotlin standard library provides vital tools that make day-to-day Kotlin programming easier. This library features the core attributes of the language, such as algorithmic problems, design patterns, data processing, and working with files and data streams. The recipes in this book offer coding solutions that can be readily executed. The book covers various topics related to data processing, I/O operations, and collections transformation. We'll walk through effective design patterns in Kotlin and you'll understand how coroutines add new features to JavaScript. As you make your way through the chapters, you'll learn how to implement clean, reusable functions and scalable interfaces containing default implementations. In the concluding chapters, we'll provide recipes on functional programming concepts, such as lambdas, monads, functors, and Kotlin scoping functions. By the end of the book, you'll be able to address a range of problems that Kotlin developers face by implementing easy-to-follow solutions. What you will learn Work with ranges, progressions, and sequences in use cases Add new functionalities to current classes with Kotlin extensions Understand elements such as lambdas, closures, and monads Build a REST API consumer with Retrofit and a coroutine adapter Discover useful tips and solutions for making your Android projects Explore the benefits of standard library features Who this book is for This book is for software developers who are familiar with Kotlin’s basics and want to discover more advanced features and concepts, especially those provided by the Kotlin standard library. It’s also ideal for experienced software developers who are familiar with the functional programming paradigm and other programming languages who want to switch to Kotlin. It will also help Java developers switch to Kotlin and integrate it into existing Java Virtual Machine (JVM) projects.
Kotlin Essentials

"Kotlin Essentials" Kotlin Essentials is a comprehensive guide designed to take developers from foundational understanding to expert proficiency in Kotlin, whether they are transitioning from Java, embracing multiplatform projects, or seeking to master advanced language features. The book opens with an in-depth exploration of modern language fundamentals, highlighting Kotlin’s expressive syntax, robust static typing with type inference, and innovative null-safety mechanisms. Readers will gain practical insights into control flow, concise function definitions, and the power of extension functions, all compared thoughtfully with Java and Scala paradigms for clear context. As the journey unfolds, the book delves into the core of Kotlin's object-oriented and functional programming capabilities. It covers advanced class structures, inheritance, abstraction, and the effective use of data, sealed, and singleton objects. Readers will discover patterns for designing extensible hierarchies, building reusable components through delegation and composition, and leveraging powerful functional constructs such as higher-order functions, immutability, and algebraic data types. The advanced type system receives thorough attention, with coverage of generics, variance, inline and reified types, and runtime reflection—ensuring robust, type-safe abstractions for any scenario. Recognizing the realities of modern software development, Kotlin Essentials expertly addresses asynchronous programming with coroutines, architectural patterns for concurrency, and multiplatform strategies for code sharing across JVM, JS, and Native targets. It guides professionals through effective collection usage, interop with Java and JavaScript, building expressive DSLs, compiling and profiling for performance, and best practices in testing, deployment, and scaling. Whether developing Android apps, server-side systems, or cutting-edge multiplatform solutions, this book provides a complete and authoritative resource for mastering Kotlin in production settings.
