Density of population

Prerequisites

• JDK 13

Build project

./gradlew build

Run tests

./gradlew test

Run the app

Run the app from gradle command line with JSON content seems to be quite challenging.
This github issue has been added in 2016 and seems to be fixed in v3.3 but I didn't succeed to run the app from CLI with JSON arg.
Broken command example: ./gradlew run --args='--densest {\"n\":2}'

Note: I mainly used unit tests during development

Compute the number of POIs in an area

You can run this directly in your IDE with program arguments: --nbpoi {\"min_lat\":6.5,\"min_lon\":-7}'

Fetch the densest areas

You can run this directly in your IDE with program arguments: --densest {\"n\":2}

POI implementation

In my app, 2 POIs should be equal if they have same id and coordinates. I suppose 2 POIs should have the exactly same latitude and longitude.

TSV file location

When you run the project the POIs are defined in a tsv file located in src/main/resources/config.tsv
