OK.  I go to

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
and download the JDK,
   jdk-8u101-linux-x64.tar.gz
Next, I double click on that file, and extract the files to
   /home/jdgalt/Programming/Java
which creates the folder /home/jdgalt/Programming/Java/jdg1.8.0_101 .

This exhausts the instructions given at

https://docs.oracle.com/javase/8/docs/technotes/guides/install/linux_jdk.html#BJFGGEFG
so I don't know what to do next.  I'm guessing there are paths and other
settings that need to be done before Java will run.

Now, what am I doing wrong?
