问题
I'm following the GeoTools documentation and found this:
GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory(null);
Coordinate coord = new Coordinate(45, 15);
Point point = geometryFactory.createPoint(coord);
When I put it in intellij IDE, for each class there are several suggested imports to use. What import I need to select?
Alternative way (with same issue) is:
GeometryBuilder builder = new GeometryBuilder(DefaultGeographicCRS.WGS84);
Point point = builder.createPoint(45, 15);

When in doubt you can always read the documentation, for example JTSFactoryFinder returns a com.vividsolutions.jts.geom.GeometryFactory
, once you know that the other pieces fall into place as:
import com.vividsolutions.jts.geom.Coordinate;
import com.vividsolutions.jts.geom.GeometryFactory;
import com.vividsolutions.jts.geom.Point;
Meanwhile your GeometryBuilder is an org.geotools.geometry.GeometryBuilder
which leads to the following imports:
import org.geotools.geometry.GeometryBuilder;
import org.geotools.referencing.crs.DefaultGeographicCRS;
import org.opengis.geometry.primitive.Point;
