How to install JDK8 on Ubuntu 16?

I needed JDK 8 for Bazel. I ran sudo apt-get install openjdk-8* on a freshly built Ubuntu 16.04.02 machine, but after installation update-alternatives --config java show two paths:

/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java
/usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java

I purged opensdk-8* and then installed apt-get openjdk-9* but the outcome was the same.

How do I get JDK 8?
