An integrated development environment (IDE) makes writing code easy. Visual Studio Code is an IDE that works well with a variety of programming languages, including Java ☕. This tutorial describes how to set up Visual Studio Code with Java, so you can create Java programs with ease.

Step 1: Install Visual Studio Code

  1. Download the Visual Studio Code installation program for your operating system.
  2. Double-click the installation program to run it.
  3. Accept all defaults during the installation process.

Step 2: Install Java

This tutorial installs OpenJDK, the free and open-source version of Java.

  1. Download the OpenJDK installation program for your operating system.
  2. Double-click the installation program to run it.
  3. Accept all defaults during the installation process.

Step 3: Creating a Java Project

  1. Start Visual Studio Code:
