How do I use antialiasing in Java?
John Zukowski In your paint() method, add the following hint at the top of the method:
((Graphics2D)g).setRenderingHint (RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
[FAQ Manager Note] This will only work in Java2. In JDK 1.x, you cannot perform antialias automatically (you would have to write your own antialiasing routines)
