编写一个java的应用小程序。,public class RandomNum{ public static void main(String[] args) { int num=(int)(Math.random()*800);//取800以内随机数 System.out.println("所取随机数为："+num); System.out.println("它的百位数字为："+(num/100));//取百位 System.out.println("它的十位数字为："+((num-(num/100)*100))/10);//取十位 System.out.println("它的十位数字为："+(num%10));//取个位 }}
