Posted by: JiafanZhou Posted on: 2007-02-22 06:57 Look at your exception here.. ArrayIndexOutOfBoundsException, at your YangHui.class line9...It is a very very simple Java program. Now what the job left for you to do is to find out why this is out of bound. Don't look at me, I am not going to do that for ye... Regards, Jiafan
