If you want to go with Oracle Java, then you can follow http://tipsonubuntu.com/2016/07/31/install-oracle-java-8-9-ubuntu-16-04-linux-mint-18/ for easy install. This will set all paths and functionality to use.

Even though you followed instructions on how to install Oracle Java, you are using one provided by Ubuntu. The default here is just to install java and not any of the tools (like jar or javac) present in the Java Development Kit. The simplest solution is just to install one in Ubuntu.

sudo apt install openjdk-8-jdk

This will install the OpenJDK flavor of Java which is slightly different from Oracle Java, but not in ways that matter at your current level.
