判断回文数最简单实现

   long l=2332l;
  
  int i = String.valueOf(l).length();
  int j = 0;
  while (j <= (i / 2) -1 && String.valueOf(l).charAt(j) == String.valueOf(l).charAt(i - j - 1))
    j++;
  
  if (j == i / 2)
   System.out.println("Yes it is HuiWen.");
  else
   System.out.println("No it is not HuiWen.");
