After issuing apt-cache search jdk, I see both openjdk-8-jdk and openjdk-9-jdk listed. I am unsure which one I should install.

I took a look at SDK downloads from Oracle's website below, and I wasn't able to immediately find SDK 9. Why would this be the case?

If you are planning to install NetBeans then install openjdk-8-jdk because openjdk-9-jdk is not compatible with NetBeans from the default Ubuntu repositories, at least it is not compatible with NetBeans in Ubuntu 16.04. NetBeans from the default Ubuntu 18.04 and later repositories, is compatible with openjdk-11-jdk.

Another alternative is to install both openjdk-8-jdk and openjdk-9-jdk and use either update-alternatives (which is installed by default in Ubuntu) or update-java-alternatives (which is installed when openjdk-8-jdk is installed) to manually choose which Java to use before running an application. See update-java-alternatives vs update-alternatives --config java.
