Java, not applicable for the arguments,affine transform?

public void paint(Graphics g) {
        Rectangle rectangle = new Rectangle(100,100,100,100);
        Graphics2D g2d = (Graphics2D) g;
        AffineTransform transform = new AffineTransform();
        transform.rotate(
                Math.toRadians(45), rectangle.getX() + rectangle.width/2,
                rectangle.getY() + rectangle.height/2
        );
        g2d.draw(transform); 
}

I am trying to rotate a rectangle around a center, but its not working. I am getting this error:

The method draw(Shape) in the type Graphics2D is not applicable for the arguments (AffineTransform)

The error indicates that you cannot call this method with transform.

You should try to call setTransform first and then draw the rectangle.

public void paint(Graphics g) {
        Rectangle rectangle = new Rectangle(100,100,100,100);
        Graphics2D g2d = (Graphics2D) g;
        AffineTransform transform = new AffineTransform();
        transform.rotate(
                Math.toRadians(45), rectangle.getX() + rectangle.width/2,
                rectangle.getY() + rectangle.height/2
        );
        g2d.setTransform(transform);
        g2d.draw(rectangle); 
}
