TL;DR – The Java version verification helps you identify the version of Java installed on your device. Additionally, you will be able to run the Java update check to confirm whether you can install a new version.

What is a Java version?

Java version numbers indicate the releases of the Java software. The newer versions have more sophisticated features, improved performance, and better security measures.

Being up to date is necessary for preventing unwanted issues that can impact stability and security. In many cases, some applications and websites are unable to run unless you install the latest version of Java. For instance, it lets you play small online games, view 3D images, and chat with people.

The Java software is available for multiple operating systems, including Windows, Mac, Linux, and Solaris.

How to verify Java versions?

There are multiple methods you can use to verify the Java version: accessing the verification page, using the Command Prompt, and utilizing the Java Control Panel.
