TO Feng Dance Phoenix: There is no exaggeration, if you use your way, the interval symbols such as the comma are removed, but there is no Xiangzhuang watch to be printed. To Sankxuan: used StringTokenizer (A, Separators, True) The three-parameter constructor, beautiful, is indeed the best implementation. -------------------------------------------------- ---- Reconstruction, the following is the reconstructed code and execution results:
