How to install JDK 11 under Ubuntu?

Question

So Java 11 is out. Does anybody know how to install it (OpenJDK from Oracle) from the command line?

I would like to see something like it was before for Oracle Java

Answer 1

Now it is possible to install openjdk-11 this way:

sudo apt-get install openjdk-11-jdk

(Previously it installed openjdk-10, but not anymore)
