Project Loom Demonstration - JVM Meetup #59

Introduction

Welcome to the Project Loom demonstration for JVM Meetup #59. This repository contains various Java applications designed to showcase the capabilities and features of Project Loom, a part of the Java Project aiming to simplify concurrency in the Java platform.

Project Loom introduces a new concept of virtual threads, offering a lightweight and efficient way of handling concurrency in Java applications. In this demonstration, we will explore different scenarios where virtual threads can be utilized, ranging from simple initialization to CPU-intensive tasks.

Folder Structure

The repository is organized into the following structure:

├── Makefile
├── Readme.md
├── cpu-intensive-virtual-thread
├── exception-virtual-thread
├── init-virtual-thread
├── massive-virtual-thread
├── pinned-virtual-thread
├── thread-overflow
└── thread-pool

Prerequisites

Each subdirectory contains a specific Java application demonstrating a unique aspect of virtual threads.

Prerequisites

• Java JDK 21 or higher
• Gradle 8.4 or higher

Commands

Building the Project
