Can I remove the older versions and do I need multiple versions of Java installed on my system?

This article applies to:

Yes, you can safely remove older versions of Java from your system by following the instructions on: Windows Java uninstallation instructions page

The latest version of Java is always the recommended version as it contains updates and improvements to previous versions. The latest available version is always compatible with the older versions.

You can also keep older versions of Java installed, in case you have an applet/application that still depends upon a previous version.

To download the latest and recommended version, please visit:
Java Download.

Note: You should report to the applet provider/developer about this dependability. They need to rectify their code in order to ensure compatibility with all Java versions.
