Half the battle is figuring out which JDK (or is it JRE??) version to install. I still have nightmares navigating the maze which is Oracle's site and trying to find the right download, only to have installed the wrong thing.
Installing the latest OpenJDK LTS release will almost certainly work for you. Java is pretty good about backwards compatibility. I'm not sure when you last tried, but you probably don't need to muck around with Oracle JDK builds at at all.
