Running Ubuntu 16.04 on a Dell E6510 Laptop.
I bought the book
JAVA All-In-One for dummies and was trying to install Java 9 JDK, JRE, JVM, Java SE etc. per the books instructions.
It is obsolete or something and steered me to try Installing Java 11 as below.
This does't work either. The Synaptic Package Manager doesn't seem to have anything either. I am totally lost here and don't know where to go next except back to PHP and Javascript.

Package oracle-java11-set-default is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
oracle-java12-set-default oracle-java11-set-default-local
E: Package 'oracle-java11-set-default' has no installation candidate
