How to have rotated Ellipse shape in Java?

Question

How to have rotated ellipse Shape in java? I.e. so that its semi-axes are not parallel to coordinate axes?

P.S. I need not just draw this ellipse but have it in memory as a shape object.

Answer 1

Just take an Ellipse2D object and apply an AffineTransform rotation to it, no?

AffineTransform.getRotateInstance(Math.PI / 4)
  .createTransformedShape(new Ellipse2D.Double(0, 0, 2, 1));
