Once again I'm doing Java graphics (Graphics2D) but I noticed there is no Polygon.Double or Polygon.Float classes whereas there is Rectangle2D.Float and Rectangle2D.Double class.
Does anyone know why this is? I just need to draw a triangle using doubles as points.
You can use a Path2D (or a Path2D.Float or Path2D.Double) to get the same effect.
