How to install the Java JDK using Temurin on Windows

There are many ways to install the Java JDK on Windows, previously the Oracle JDK was used, but now since Oracle has made changes to the use license, it is recommended to use either the OpenJDK or one of the many distributions that exist, which are based on OpenJDK and add improvements and optimizations. One of the most popular is the Adoptium distribution, previously known as AdoptOpenJDK, which offers OpenJDK builds for different operating systems and architectures. Eclipse Temurin is the name of Adoptium's OpenJDK distribution. One of the advantages over OpenJDK is that Temurin offers long-term support, which means that security updates and bug fixes will be received for a long time.

In this article we will see how to install the Java JDK using Temurin on Windows and the considerations that we must take into account so that everything works correctly.

Download Temurin

To install Temurin on Windows, the first thing we must do is download the installer from the official Adoptium website. To do this, we access https://adoptium.net/es/. Once on the page, the most direct way is to click on the Latest LTS Version button, this will automatically download the installer for the most recent LTS version of Temurin, in this case version 21 (approximately every 3 years a new LTS version is released).

In case we want to download a specific version we can click on the Other platforms and versions button and start filtering by operating system, architecture, package type and Java version.

Install Temurin

Once the installer is downloaded, we double click on it to run it. Next, an installation window will open in which we must click on the Next button to begin the installation process. In the next window, we accept the license terms and click Next. We select if we want it to be installed only for the current user or for all users and click on Next.

In the last window of custom installation it is important to take into consideration the following options:

• Add the installation directory to the system PATH.
• Associate .jar files with Adoptium (allows you to execute .jar files by double clicking on them).
• Create or overwrite the JAVA_HOME environment variable with the Adoptium installation path.

In case this is the only version of Java that we are going to have installed on the system, we can leave these options selected, but if we have several versions of Java installed, it is advisable to uncheck these options, since we could have some inconveniences when running some applications or working with IDEs such as Eclipse or IntelliJ IDEA, since these use the JAVA_HOME environment variable to know which version of Java to use.

Note: We can always manually configure these environment variables in case we have not configured them during the installation, we can take as reference the following post https://asjordi.dev/blog/como- install-java-openjdk-on-windows which explains how to configure environment variables in Windows.

Finally, we can change the installation path, personally I prefer to install it in the folder C:jdk-version, where version is the version of Java that we are installing, for example C:jdk-21. Once the options are configured, we click on Next and then Install to begin the installation. When finished, we click on Finish to close the installer.

Verify installation

To verify that the installation was successful, we open a Windows terminal and execute the following command:

java -version

If everything is correct, we should see a message similar to the following.

In case it displays an error message, the JAVA_HOME environment variable may not have been set correctly or the installation path may not have been added to the system PATH. To do this, you can review the post mentioned above where it explains how to configure environment variables in Windows.

These are all the necessary steps to install Temurin on Windows, it is just a matter of following the installation wizard and having the necessary considerations regarding the environment variables so that everything works correctly.
