Polygons with Double Coordinates

Question

I have some questions about Polygons with points of Double type... What I have to do, is given points, create the polygon, and then, test if 1 concrete point is inside the poly

Answer 1

You can do this with Path2D.Double:

Path2D path = new Path2D.Double();

path.moveTo(valoresX[0], valoresY[0]);
for(int i = 1; i < valoresX.length; ++i) {
   path.lineTo(valoresX[i], valoresY[i]);
}
path.closePath();
