This is the code repository for Learning Concurrency in Kotlin, published by Packt.

Take advantage of Kotlin's concurrency primitives to write efficient multithreaded applications

The primary requirements of modern-day applications are scalability, speed, and making the most use of hardware. Kotlin meets these requirements with its immense support for concurrency. Many concurrent primitives of Kotlin, such as channels and suspending functions, are designed to be non-blocking and efficient. This allows for new approaches to concurrency and creates unique challenges for the design and implementation of concurrent code. Learning Concurrency in Kotlin addresses those challenges with real-life examples and exercises that take advantage of Kotlin's primitives.

This book covers the following exciting features:

• Understand Kotlin’s approach to concurrency and how it is different to that of Java’s
• Implement suspending and asynchronous coroutines
• Understand how to decide which thread to execute a coroutine
• Create potentially infinite data streams that are loaded lazily and concurrently
• Explore the best practices for error handling

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

val time = measureTimeMillis {
        val name = async { getName() }
        val lastName = async { getLastName() }

        println("Hello, ${name.await()} ${lastName.await()}")
    }

Following is what you need for this book: If you’re a Kotlin or Android developer interested in learning how to program concurrently to enhance the performance of your applications, this is the book for you.

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