I installed the java jre via my package manager and get this version:
$ java -version
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)
But the current Java Update is 71, so I downloaded it from the official website, but I don't know how to install the download and what exact file I should download. How do I do that? I use Ubuntu 14
