Do I Need All These Versions of the JDK..I mean the JRE files?

I downloaded the JDK and am wondering if I need all these versions that begin with JRE or can I delete all but the most recent. These is what I have. I'm not quite sure if some are duplicates of older versions or not.

jdk1.6.0_11

jre1.6.0_01

jre1.6.0_04

jre1.6.0_07

jre6

Thanks.

I guess it's best to keep one jre installation (usually the latest update).

However rather than deleting better use the uninstallation options through control panel in Windows.

If you are on Linux I am not sure what you have to do to remove them.

Most Linux distributions come with a package management system. When there's a new version of Java, the package management system announces to the user that there's an update, and it automatically removes the old version and installs the new version.

On Windows, the Java updater unfortunately seems to leave old stuff lying around.

Ah, thanks very much. I was hoping I could get rid of some of the updates. Yes, I am using Vista so I will delete with the control panel. It's a shame it doesn't automatically remove the old version after the update.

I am loving learning this language. There is a beauty in it.
