Hello. I am trying to download java, because for some reason it does not seem to come with Ubuntu. I tried to follow the directions at the website, but I did not understand most of the directions. I tried a YouTube tutorial, with rootilus used to place the file in the usr/lib/jvm/ file, but in addition to not working, it also seems to have removed the jvm file. I have no idea what to do, because I can't just make a new folder called jvm because Ubuntu does not allow it, it is just grayed out. I don't have a clue what to do.
