It is correct that you should use the OSM format directly. Whether you want to load that into PostgreSQL or not is another question, you could also load it into memory or process it into a proper routing graph right away. > Question is how is build graph in Java and find way between nodes and it > details?

If you want something out-of-the-box, you can use osm2pgrouting and try the PostgreSQL "pgrouting" extension on that but it will not be very fast. There is also a specialist mailing list called "routing" on the OSM server where people talk about these things.
