答案 0 :(得分：1)
您已撰写int no_of_rows = list_productname.size()。所有arraylist的大小是否大于或等于list_productname的大小是否意味着如果任何arraylist的大小小于list_productname那么将导致ArrayIndexOutOfBoundsExcption。
因为你循环从几个arraylist获取数据，直到你达到list_productname大小是错误的。由于这个逻辑而受到影响的其他数组列表是list_productid, list_offername, list_offerid等。你可以认为其他arraylist的数据数量最少no_of_rows。
