输入一个数n，打印出从1到n之间只包含3或5的倍数和，例如n=17，则求和的数为：3,5,6,9,10,12,15.

package java_two;

import java.util.Scanner;

public class Classfour {

	public static void main(String[] args) {
		System.out.println("请输入一个数n=");
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		int s = 0;
		int i;
		System.out.println(n);
		for(i = 1; i <= n; i ++)
		    if(i%3==0 || i % 5 == 0)
		        s+=i;
		    System.out.println(s);
		}
