Learning Concurrency in Kotlin

By: Miguel Angel Castiblanco Torres

Overview of this book

Kotlin is a modern and statically typed programming language with support for concurrency. Complete with detailed explanations of essential concepts, practical examples and self-assessment questions, Learning Concurrency in Kotlin addresses the unique challenges in design and implementation of concurrent code. This practical guide will help you to build distributed and scalable applications using Kotlin. Beginning with an introduction to Kotlin's coroutines, you’ll learn how to write concurrent code and understand the fundamental concepts needed to write multithreaded software in Kotlin. You'll explore how to communicate between and synchronize your threads and coroutines to write collaborative asynchronous applications. You'll also learn how to handle errors and exceptions, as well as how to work with a multicore processor to run several programs in parallel. In addition to this, you’ll delve into how coroutines work with each other. Finally, you’ll be able to build an Android application such as an RSS reader by putting your knowledge into practice. By the end of this book, you’ll have learned techniques and skills to write optimized code and multithread applications.

Testing and Debugging Concurrent Code

One of the biggest challenges with concurrency is that bugs are often found late in the development process. Often, a concurrency error will first be seen in a production environment, when Murphy's law becomes a reality and all the things that can go wrong actually do go wrong.

This is because many of the bugs related to concurrency will happen during edge cases that either are thought of as impossible, or are so unlikely that they didn't even cross the minds of the developer or the code reviewers. This chapter aims to provide you with some advice on how to write tests that can help you to identify the scenarios you aren't prepared to handle, as well as some information on how to successfully write logs and debug your coroutines.

The topics in this chapter are interleaved with general advice that may not be directly related...
