This will generate a HelloWorld.class file. Once done, you can open the terminal - on Mac OS, type ⌘+` - and then type javac HelloWorld.java to compile the file. Start by creating a HelloWorld.java file and open on VS Code (or create the file within and then save in some folder). Once you install language support, you can read and edit Java source code. All other extensions are complementary but do consider them based on the types of projects you'll be working on. This is the one and the only extension you are required to install to have Java support. This extension pack bundles the five extensions below explained in detail, and it will help you get started without digging too much. There is a set of extensions that are the minimum requirement to get core Java support in VS Code. But check this guide below for a laser-focused walkthrough in getting the most out of VS Code for Java development. You can also skip this guide completely and simply go to the documentation page for Java in Visual Studio Code.

The rest of this guide will assume you have at least Java 8 installed, though it works with Java 11, too. If you haven't already downloaded Visual Studio Code, install it now. Here's the ultimate guide of 2019 for Java developers to use Visual Studio Code to develop, run, debug, and deploy their applications. Unsurprisingly, VS Code can do Java as well, and many Java champions and speakers have chosen it for their on-stage appearances and live demos.

Javascript, TypeScript, Go, Python, and other languages have a massive amount of developers coding through VS Code, in part thanks to the huge ecosystem of extensions that enhance and enrich the experience in VS Code, turning it into a super smart text editor with IDE-ish capabilities while remaining ludicrously fast and lightweight. Visual Studio Code has come a long way to become the preferred text editor of polyglot developers.
