Tutorial: Java and Visual Studio Code

An integrated development environment (IDE) makes it easy to write code.

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 and write your first Java program.

Step 1: Install Java

  1. Download the OpenJDK LTS release.
  2. Double-click the file.
  3. Accept all defaults during the installation process.

Step 2: Install Visual Studio Code

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

Step 3: Creating a Java Project

  1. Start Visual Studio Code:

  9. If the Java Help Center window appears, click the x button to dismiss it. Then in the left window pane, expand MYJAVAPROJECT > src and click App.java to show the program in the editor window. App.java is a sample program that Visual Studio Code provides when you create a new Java project:

  10. Wait a few seconds, then you will see Run and Debug links above the main() method declaration in the editor window. Click the Run button to run the Java program:

  11. Note the output of the program in the terminal window below the editor window:

  12. To create a new Java program in the project, right-click the src folder and click New File. Type a program filename, e.g., HelloWorld.java and press the Enter key. Now edit your new Java program in the editor window.
