Fill rectangle with pattern in Java Swing

I know how to fill a rectangle in Swing with a solid color:

Graphics2D g2d = bi.createGraphics();
g2d.setColor(Color.RED);
g2d.fillRect(0,0,100,100);

I know how to fill it with an image:

BufferedImage bi;
Graphics2D g2d = bi.createGraphics();
g2d.setPaint (new Color(r, g, b));
g2d.fillRect (0, 0, bi.getWidth(), bi.getHeight());

But how to fill rectangle of size 950x950 with some tiled pattern of size 100x100?

(pattern image should be used 100 times)
