The Best Way to Check Your Java Version on Windows 11

Microsoft To determine the Java version installed on your computer, use the Java version command in a Terminal window. If you have multiple Java versions installed, opening the About Java box from the Start menu can display a different version of Java that isn't currently in use. Utilize the Terminal to Verify Your Java Version. Whether you're using Windows 11 or Windows 10, there are many ways to find out what Java versions you have installed. Sometimes software will suggest or need a certain Java version in order to work. If you have installed multiple Java versions, the issue grows worse. What makes you aware of the version you're using? Fortunately, all you require is one command. For instance, to get Java versions, simply type "About Java" into the Start Menu search bar and click the result. However, if you launch a JAR file, that doesn't always show the version your system would really try to utilize. The mismatch arises as a result of the simultaneous installation of many Java versions. You just need to be aware of whatever version you're actually using, which is typically not an issue. The Terminal is the best tool to use to find out which version of Java is installed on your computer. It makes no difference whether you employ PowerShell or Command Prompt. Tap I to launch Terminal after pressing Windows+X to access the Power User Menu. As an alternative, you can click Start and type "Terminal" into the search field. Hit Enter after entering the Java versions in the Terminal. Under your command, your Java versions will be shown in the Terminal. Then, installed on our example PC is 17.0.4.1, as seen in the screenshot above. You must adjust your system's environment variables, notably the PATH, to alter the Java versions that is currently in use. You can change environment variables using CMD or the standard Windows graphical user interface.
