    public Point2d(double[] p)

  Constructs and initializes a Point2d from the specified array.

  Parameters:
    `p` - the array of length 2 containing xy in order

### Point2d

    public Point2d(Point2d p1)

  Constructs and initializes a Point2d from the specified Point2d.

  Parameters:
    `p1` - the Point2d containing the initialization x y data
