A short note about HowTo install and set a specific Java version when you have various versions installed.
Will use the archlinux-java script, see the Switching between JVM.
Install a package itself, here it will be Oracle Java 14:
yay -S jdk

:: Checking for inner conflicts...
[Aur: 2] jre-14.0.1-1 jdk-14.0.1-1
...
Check currently used – in this case, it’s old OpenJDK 11:
java --version
openjdk 11.0.6 2020-01-14
OpenJDK Runtime Environment (build 11.0.6+10)
OpenJDK 64-Bit Server VM (build 11.0.6+10, mixed mode)
List all installed versions:
archlinux-java status
Available Java environments:
java-11-openjdk (default)
java-14-jdk
java-8-jdk
Set the Oracle Java 14 as the active version to be used by default now:
sudo archlinux-java set java-14-jdk
Check again:
java --version
java 14.0.1 2020-04-14
Java(TM) SE Runtime Environment (build 14.0.1+7)
Java HotSpot(TM) 64-Bit Server VM (build 14.0.1+7, mixed mode, sharing)
Done.
