To update Java 17 to Java 18, you must uninstall Java 17 and install Java 18.

Update to a minor Java version

To update Java 17.0.1 to Java 17.0.5, you can make Java itself check and update to the latest minor version for you.

Update to the Major Java Version

You can update the major Java version in two steps:

1. Uninstall the old Java version

Open the Start menu and search for Apps and Features.

Open it, and you will get a list of applications on your computer.

Search for the Java SE Development Kit and uninstall it. If you see the Java application on this list, uninstall it as well.

And you are done.

Now it's time to install the new Java version you are updating.

2. Install the new Java version

The easy way to install Java in Windows is to install the Java installer from the official site.

Go to Oracle, and go to the Windows section.

Make sure you navigate to the Java version of your choice. Once you reach this page, download the Installer.

Once the download is complete, open the installation file. The prompt will ask for permission and lead you to the installation.

After a few easy steps, Java will download on your computer.

To check if the installation was successful, run the command again

java --version

This is the output in my command prompt.

As I've successfully installed Java 19, the command prompt shows the Java version installed on your system.
