Demo code showing how to use Java's virtual threads.

Virtual Threads Examples

This repository contains several examples for "Virtual Threads", a feature described in JEP 444 and released in Java 21.

I use these examples in my presentations on virtual threads.

Java 21 IDE Support

IntelliJ IDEA supports Java 21 as of version 2023.2.2. As long as this version is not yet released, you can install the release candidate via the JetBrains Toolbox App by going into the IntelliJ IDEA settings and activating the "Early Access Program".

Java Downloads

You can download Java 21 from here: https://jdk.java.net/21/

To install multiple Java versions on Linux or macOS, I recommend using SDKMAN!

To install multiple Java versions on Windows, have a look at this tutorial: How to Change Java Versions in Windows
