Installation instructions on Windows

  • Step 0: Adjusting your keyboard language
  • Step 1: Install VSCodium
  • Step 2: Install a JDK
  • Step 3: Verify the JDK Installation

Step 0: Adjusting your keyboard language

While using the software for this course, your computer’s keyboard language must be set to English. If needed, please follow these instructions to change your keyboard language.

Step 1: Install VSCodium

  1. Go to the VSCodium releases page.

  2. Scroll down to the table of download links for the latest release, and download the Windows user installer:

    • Most Windows laptops: choose the file whose name begins with VSCodiumUserSetup-x64 and ends with .exe.

    • Windows laptops with an ARM processor: choose the file whose name begins with VSCodiumUserSetup-arm64 and ends with .exe.

    If you are not sure which one you need, try the x64 installer.

  3. Double-click the icon for the downloaded file to start the installer. If prompted to do so, click Run.

  4. You should be able to use all of the default settings that the installer gives you. Wait for it to complete the installation and then click Finish. You can now delete the installer program.

Step 2: Install a JDK

Java programs are compiled and run using a tool called the Java Development Kit, or JDK. For this course, please install a recent version (25 or newer).

After a JDK is installed, the javac and java commands become available.

Here are the steps:

  1. Go to the Eclipse Temurin download page.

  2. Select the latest LTS version.

  3. Use the following settings:

    • Operating system: Windows

    • Architecture: x64 for most Windows laptops, or aarch64 / arm64 if you have a Windows laptop with an ARM processor

    • Package type: JDK

  4. Download the installer, which should have a name ending in .msi.

  5. Double-click the .msi file and follow the prompts to install the JDK.

Step 3: Verify the JDK Installation

  1. If VSCodium is not already open, launch it.

  2. Open VSCodium’s built-in Terminal pane. You can do this by pressing the Control key and the backtick key, or by selecting Terminal->New Terminal from the menu.

  3. In the Terminal, type the following command and then press Enter:

    java -version

    You should see output that looks similar to this:

    > java -version
openjdk version "25.0.1" 2025-10-21 LTS
OpenJDK Runtime Environment Temurin-25.0.1+8 (build 25.0.1+8-LTS)
OpenJDK 64-Bit Server VM Temurin-25.0.1+8 (build 25.0.1+8-LTS, mixed mode, sharing)

The exact version may be different, but the output should include “Temurin” and a recent Java version number.
