        while (true) ...{                                   //设计一个循环                          
            try ...{

                System.out.println("请输入一个(1-100)之间的整形数：");

                int Temp = Integer.parseInt(in.nextLine());    //从键盘接收一个数

                if (Temp < 1 || Temp > 100)             //约定 必须是1-100之间的数
                                                                                    ...{
