      • copyOf

        public static java.awt.Shape copyOf​(java.awt.Shape shape)
        Returns a shape that is (more or less) equivalent to the supplied shape. For some known shape implementations (Line2D, Rectangle2D, RoundRectangle2D, Arc2D, Ellipse2D, and Polygon) the copy will be an instance of that class. For other shapes, a Path2D containing the outline of the shape is returned.
        Parameters:
        shape - the shape (null not permitted).
        Returns:
        A copy of the shape or shape outline (never null).

      • createPolygon

        public static java.awt.geom.GeneralPath createPolygon​(int[] xPoints,
                                                      int[] yPoints,
                                                      int nPoints,
                                                      boolean close)
        Creates a polygon from the specified x and y coordinate arrays.
        Parameters:
        xPoints - the x-points.
        yPoints - the y-points.
        nPoints - the number of points to use for the polyline.
        close - closed?
        Returns:
        A polygon.
