java判断回文数示例分享

/*** 判断一个数是不是回文数，回文数就是原数与其倒置后的数相等* 如：123321，到之后仍为123321，即为回文数* @author lvpeiqiang*/public class HuiWenShu { public boolean isHuiWenShu(int num) { int s = 0; int bNum = num; int mod;  //以下为把数值倒置的方法 while(bNum != 0) {  mod = bNum%10; //123%10 = 3  s = s*10 + mod; //s = 0*10+3  bNum = bNum/10; //bNum = 123/10=12(int自动转换) } boolean b = (s == num); return b; }  public static void main(String[] args)  { HuiWenShu p = new HuiWenShu(); boolean b = p.isHuiWenShu(123321); System.out.println(b); }}
