JAVA实现数字反转

import java.util.Scanner;public class Reverse{ //输入一个整数然后反转    public static void main(String[] args){        Scanner sc = new Scanner(System.in);        System.out.println("请输入一个整数");        int num = sc.nextInt();        int result=0;        for( ; ;){            int n = num%10;            result = result*10 + n;            num = num/10;//降位            if(num==0){                break;            }        }        System.out.println(result);    }   }
