I downloaded Oracle JDK-8 using sudo apt-get install oracle-java8-installer and set this version to default using sudo update-alternatives --config java but when I run java -version I get 

java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

Have you tried using update-java-alternatives instead of update-alternatives?

Show the list of available alternatives:

sudo update-java-alternatives -l

Select one of them:

sudo update-java-alternatives -s java-1.8.0-openjdk-amd64
