Finding a simple working Java source code creating and manipulating Neo4j graph

Hi,

Can anyone help with what was seems to me a very simple task (but after few day and nights found it not a trivial task): finding a simple working Java source code creating and manipulating Neo4j graph data-base (desktop or community version Bolt or REST APIs).

Maven POM.XML is also welcomed.

My platform is Windows 10 with IntelliJ IDE.

Thanks in advance
