Kotlin Standard Library Cookbook : Master the powerful Kotlin standard library through practical code examples

Key FeaturesGet the most out of the Kotlin library to develop high-quality portable applicationsExplore the powerful support for data processing and I/O operationsDiscover ways to enhance your Android application developmentBook 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 learnWork with ranges, progressions, and sequences in use casesAdd new functionalities to current classes with Kotlin extensionsUnderstand elements such as lambdas, closures, and monadsBuild a REST API consumer with Retrofit and a coroutine adapterDiscover useful tips and solutions for making your Android projectsExplore the benefits of standard library featuresWho 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 Standard Library Cookbook

This is the code repository for Kotlin Standard Library Cookbook, published by Packt.

Build optimized applications in Kotlin by learning how to smartly implement standard libraries

Given the verbosity of Java, developers have turned to Kotlin for effective software development. Apart from being a modern programming language, 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.

This book covers the following exciting features: 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 Coroutines adapter Discover useful tips and solutions to make your Android projects Explore the benefits of the standard library features

Instructions and Navigations

Almost all recipes are present in the Kotlin-Samples directory, however, the separate projects that are created target JS and Android. Inside the Kotlin-Samples directory there is the content of the main project with pure Kotlin samples.

The code will look like the following:

val daysOfYear: IntRange = 1..365 for(day in daysOfYear.reversed())

Following is what you need for this book: 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.

With the following software and hardware list you can run all code files present in the book (Chapter 1-9).
