Readme: The version code fixes the problem of disorder print, which results from the fact that the statement of System.out.printf() isn’t synchronized. so i move coresponding statements to the synchronized method, then this problem is solved smoothly. ^_^ Maybe there is version 3, who knows, if i am available and don’t forget this problem. *_*
