The Geocoding in Java with the Google Maps API tutorial provides a comprehensive guide on how to set up a simple Java Spring Boot application that queries and packages data from the Google Maps API. The tutorial covers creating a project, obtaining an API key, setting up dependencies, and mapping the response to custom Java objects. It also includes examples of how to handle responses, errors, and edge cases. The final application returns a `GeocodeResult` object that can be easily sent around an application.
