Cannot use Base as Java missing

I am attempting to sign into Libre Office BASE but am unable to.
I receive the messages:
The connection to the database cannot be established and No java installation could be found. Please check your installation

Please help if you can
Thank you

From your screenshot(s), I see, that your are on macOS - you need to install JDK (Java Development Kit - JRE doesnt work on macOS). Check here:

JDK 8: Java SE Development Kit 8 - Downloads

JDK 14: https://www.oracle.com/java/technologies/javase-jdk14-downloads.html#license-lightbox

AdoptOpenjdk Latest release | AdoptOpenJDK - Open source, prebuilt OpenJDK binaries

How to install Java (JRE/JDK) so that LibreOffice could use it?

Thank you - this worked.
