Builds a small Java service that stores Java versions and their diffs in Neo4j, using Spring Data Neo4j and the official Neo4j Java driver over Bolt to a Neo4j Aura instance. Data model maps versions to version-diff nodes; REST endpoints return full nodes and a lean projection implemented with a custom Cypher query. Demo returns versions up to 18 (17 is latest official), notes missing diffs for 1.0, and the API works as shown.
