How to rotate rectangle?

Here is an example of drawing the left leg of my character:

g2d.fillRect(pX + (headW - bodyW)/2, pY + headH + bodyH, legW, legH); //left leg

I know how to rotate images with AffineTransforms, like this:

AffineTransform tr = g2d.getTransform();
tr.rotate(Math.toRadians(rotAmount));
g2d.drawImage(playerI, tr, null);

How can I rotate this rectangle with an AffineTransform? I can't do something like:

g2d.rotate(Math.toRadians(rotAmount));

Because that rotates my entire person. How can I rotate only the leg?

Never mind, I found out how.

AffineTransform old = g2d.getTransform();
g2d.rotate(Math.toRadians(lLegRot));
g2d.fillRect(pX + (headW - bodyW)/2, pY + headH + bodyH, legW, legH); //left leg
g2d.setTransform(old);
g2d.rotate(Math.toRadians(rLegRot));
g2d.fillRect(pX + headW - legW - (headW - bodyW)/2, pY + headH + bodyH, legW, legH); //right leg

Newer rotations override older ones while keeping the previously rotated thing intact. To reset rotation just do g2d.setTransform(old);.

If you decide to use java.awt.geom you can make that with rotate(someAngle) method.
