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.

Summary

This chapter was all about collaborative concurrency. We were able to cover many different topics, from practical and technical points of view. Let's recap the chapter to keep the knowledge fresh:

  • We discussed some real-life examples of using channels to solve challenges related to collaborative concurrency.
  • We learned that channels are a communication tool, allowing us to safely send messages between coroutines regardless of their thread.
  • We talked about unbuffered channels. These are channels that will suspend send() until receive() is called for each element.
  • We also covered three different types of buffered channels: ConflatedChannel, which keeps only the last element that was sent; LinkedListChannel, which will never suspend when send() is called because it can hold unlimited elements – or at least as many as possible in the available memory; and ArrayChannel...
