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.
