Rectangle2D getY () returns a value less than getMaxY ()

As I interpret the documentation, getY () should return the y-coordinate of the upper left corner of the rectangle; that is, the largest Y coordinate. However, when I call getMaxY () (which is inherited from the RectangularShape class), I return a larger value!

In code:

Path2D bg = polygons.get(polyId2GeoId.get(id));
Rectangle2D bgBox = bg.getBounds2D();
boolean omgwtfbbqrsvp = bgBox.getY()<bgBox.getMaxY();

omgwtfbbqrsvp is true ... What am I missing here?

My x values ​​contain negative idk numbers if that matters. It looks like bgBox.getY () == bgBox.getMinY () (which is not true if getY is top ), but bgBox.getX () == bgBox.getMinX () (this is correct if getX is left ). Height and width are displayed correctly.

Thank!

The problem is that the coordinate system used here has its point (0,0) in the upper left corner. Point (n, n) is in the lower right corner.
