How do I restore my java utilities folder?

Hey, in a stupid attempt to troubleshoot something, I ended up entirely deleting the Java folder from my Utilities folder. Now Java doesn't work, the Updater doesn't give me anything, and trying to download and install any version of compatible java off the java site has given me the error of "your computer doesn't need this update"

Is it possible, perhaps, to just redownload that folder? or should I try to completely remove java from my computer so I can finally re-install it?

I feel like such a moron for doing this to myself. haha.
