are all these java updates necessary?

Just cleaning my computer a bit and noticed several java updates in my programs list. Are these necessary or do I just need the most recent one? They're all around 100mb a piece and each one is slightly larger than the last so I assume the other updates are unnecessary.

You just need the last one, uninstall all the previous.

The newer versions when installed, will automatically uninstall the previous version, so this won't have to be done anymore. Started with version 10 or 11 IIRC. Really not sure when the install routine got smart, but I'm at 13 now and didn't have to manually uninstall the prior version.

Uninstall all the old ones. The new ones wont do that.
