can not having Java installed be more dangerous?

I mean does it make one vulnerable to infections?

 

My java is deleted and I can't seem to reinstall. So far I do not notice any difference in functioning

 

But for some odd reason, in my IE addons, it shows  a java BHO  (jp2ssv.dll) I shows it in a java folder that I am not able to locate. Should I disable this item in my browser?
