In this article, I will show you how to setup OpenJDK 17 on Windows operating system. You know, OpenJDK is a production-ready, open-source distribution of Java Development Kit (JDK). And JDK 17 is the latest Long Term Support (LTS) release of Java SE platform, as of October 2021.

 

1. Download binary distribution of OpenJDK 17

Head over to the official download page of OpenJDK at https://jdk.java.net/17, and click on the link for Windows/x64:

It will download the binary distribution of OpenJDK 17 as a ZIP archive file. Then you should type the following command to verify the SHA256 checksum of the downloaded file:

certutil –hash openjdk-17_windows-x64_bin.zip SHA256

Compare the SHA256 value produced by this command against the value posted on the website, in the corresponding sha256 link. If they are identical, it’s safe to use the downloaded zip file.

 

2. Install OpenJDK 17 on Windows

Extract the zip file into a directory on your computer, e.g. D:\OpenJDK17. Then you need to update the JAVA_HOME environment variable, pointing to the installation directory of OpenJDK 17, e.g. D:\OpenJDK17\jdk-17. Also make sure that the PATH variable does include an entry to JAVA_HOME’s bin folder:

setx –m JAVA_HOME “D:\OpenJDK17\jdk-17”

setx –m PATH “%JAVA_HOME%\bin;%PATH%”

Note that you must execute these commands with administrator right. Follow this article to learn more.

Then open a new command prompt and type java –version to verify:

If you see this screen, it means that OpenJDK 17 has been successfully installed.
