Kotlin Coroutines on Android - How to use Coroutines on Android

Kotlin Coroutines on Android - How to use Coroutines on Android

Coroutines are a Kotlin feature that convert async callbacks for long-running tasks, such as database or network access, into sequential code. This Kotlin Coroutines tutorial will show you how to use coroutines on Android, and how the new androidx-concurrent library makes it easy to use them to get things off the main thread. You'll also learn how the new library helps coroutines work with Architecture Components. This session also covers coroutine patterns, best practices, and even how to test coroutines!

What's New in Java 19: The end of Kotlin?

What's New in Java 19: The end of Kotlin?

What's New in Java 19: The end of Kotlin? Will Kotlin still have a place in the JVM language ecosystem in a few years? This tutorial will compare and contrast how the two languages approach solving the same problems of today's Java. We'll peer a few years into the future to see where both languages are headed and determine whether we still need a Kotlin

Kotlin's introduction was a breath of fresh air at a time when the pace of innovation in Java felt glacial. Since that time, development of Java has rapidly increased with an emphasis on fixing the pain points of the language and the efficiency of data representation in the VM. Will Kotlin still have a place in the JVM language ecosystem in a few years?

This talk will compare and contrast how the two languages approach solving the same problems of today's Java. We'll look at data-carrying types, asynchronous programming, nullability, and more. For some of these, we'll also see how one language sometimes influenced the other. Finally, we'll peer a few years into the future to see where both languages are headed and determine whether we still need a Kotlin (spoiler: we probably do!).
