是否有java实现方式

是的，Java也可以使用相似的库来实现泰森多边形的创建。下面是一个使用 JTS Topology Suite 库的Java示例代码：

import java.util.ArrayList;
import java.util.List;
import org.locationtech.jts.algorithm.ConvexHull;
import org.locationtech.jts.algorithm.DelaunayTriangulationBuilder;
import org.locationtech.jts.geom.Coordinate;
import org.locationtech.jts.geom.Geometry;
import org.locationtech.jts.geom.GeometryFactory;
import org.locationtech.jts.geom.MultiPolygon;
import org.locationtech.jts.geom.Polygon;
import org.locationtech.jts.geom.PrecisionModel;
import org.locationtech.jts.geom.impl.PackedCoordinateSequenceFactory;

public class Voronoi {

    public static void main(String[] args) {
        // 输入一组经纬度坐标点
        Coordinate[] coords = new Coordinate[] {
            new Coordinate(116.404, 39.915),
            new Coordinate(116.418, 39.921),
            new Coordinate(116.434, 39.907),
            new Coordinate(116.388, 39.908),
            new Coordinate(116.401, 39.889),
            new Coordinate(116.382, 39.893),
            new Coordinate(116.387, 39.911),
            new Coordinate(116.412, 39.887),
            new Coordinate(116.408, 39.902),
            new Coordinate(116.441, 39.914),
            new Coordinate(116.428, 39.901),
            new Coordinate(116.456, 39.909)
        };

        // 创建 GeometryFactory
        PackedCoordinateSequenceFactory coordSeqFactory = new PackedCoordinateSequenceFactory(PackedCoordinateSequenceFactory.DOUBLE);
        PrecisionModel precisionModel = new PrecisionModel(PrecisionModel.FLOATING);
        GeometryFactory geometryFactory = new GeometryFactory(coordSeqFactory, precisionModel);

        // 使用 Delaunay 三角剖分算法创建三角形网格
        DelaunayTriangulationBuilder builder = new DelaunayTriangulationBuilder();
        builder.setSites(coords);
        Geometry triangles = builder.getTriangles(geometryFactory);

        // 获取凸包信息
        ConvexHull convexHull = new ConvexHull(coords, geometryFactory);
        Geometry hull = convexHull.getConvexHull();

        // 计算泰森多边形
        List<Polygon> voronoiPolygons = new ArrayList<>();
        for (int i = 0; i < triangles.getNumGeometries(); i++) {
            Geometry triangle = triangles.getGeometryN(i);
            Coordinate[] triangleCoords = triangle.getCoordinates();
            Polygon voronoiPolygon = geometryFactory.createPolygon(triangleCoords);
            if (hull.contains(voronoiPolygon)) {
                voronoiPolygons.add(voronoiPolygon);
            }
        }

        // 输出泰森多边形
        MultiPolygon voronoiDiagram = geometryFactory.createMultiPolygon(voronoiPolygons.toArray(new Polygon[0]));
        System.out.println(voronoiDiagram);
    }

}

这个示例代码将输出一个由泰森多边形组成的多边形集合。你可以根据需要进一步处理这些多边形。
