输入一个整数，判断其是否是回文数，回文数是指这个数颠倒后，和原数相同那个。...

 1 public static void main(String[] args) {
 2         System.out.println("请输入一个整数：");
 3         Scanner input = new Scanner(System.in);
 4         int sum = 0;
 5         int num = input.nextInt();
 6         int c = num;
 7         for (; num > 0; num /= 10) {
 8             sum = sum * 10 + (num % 10);
 9         }
10         String a = (sum == c) ? ("是回文数") : ("不是回文数");
11         System.out.print(a);
12     }
