How to Find the Latest JRE Version on a System
Java can easily find the Java Runtime Environment (JRE) version that is running on your system with an applet that you run through your browser. You'll need to access Java's website first; from there, the applet will automatically run (after you allow it to install). Once it finishes the scan, it will display the latest version of JRE to be installed on your system against the latest version that has been released; it will inform you if you need to update.
