Drawing a nice circle in Java

Question

I\'m using Java Graphics and I keep getting \"ugly\" circles.

Here\'s what my Java program makes

Answer 1

You can enable anti-aliasing:

Graphics2D g2 = (Graphics2D) g;
Map hints = new HashMap();
hints.put(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); 
g2.setRenderingHints(hints);

I also suggest you draw to the Graphics object you get from the paintComponent method rather than creating an intermediate BufferedImage.
