virtual-threads

A simple demonstration of virtual threads.

Overview

This project shows a familiar usage of the Thread, ExecutorService and related classes but uses the new "virtual" threads instead of traditional operating system threads (now referred to as platform threads in Java). Virtual threads were finalized in Java 21 and are described by JEP 444.

Instructions

  1. Use Java 21
  2. Run the program: 
    • java src/dgroomes/VirtualThreadsMain.java
    • It will print something like the following.
    • $ java src/dgroomes/VirtualThreadsMain.java
