How calixte-williams/set08803_gw works

This is a Java console application for querying the World database and reporting population statistics. Its principal workflow is to start the application, connect to the database, run population queries, and produce reports. The README documents country, city, capital-city, population-distribution, and language-speaker reports; the sampled App.java excerpt shows SQL execution and result mapping, but not the full report/output flow. Report capability nodes therefore reflect documented features, not separately verified modules.
