Hello-world like example for offline routing from A to B

Open Source Routing Engine

Hi there,

I am an intern at a company who produces business applications (for example solving vehicle routing). In my second week, I got the task to implement an offline routing GiS component (so far they used pythagoras). After some googling I decided to solve the problem with graphhopper. But here is the catch:

I looked at the following snippets:
https://www.viaboxx.de/route-optimization/distances-for-vehicle-routing-with-graphhopper/

And with my limited experience I couldn’t understand the vast majority of the code (where to place the osm file, how do I specify the working directory (like is it a string?) - and so on…

So I was wondering if there would be a step by step guide for offline routing in java, where I’ll be explained what for example setGraphHopperLocation(workDir) is and so on.

all the best,
David

PS: I did look into git repositories, but this is my first time building real software, so I am very unfamiliar with the process.
