JAVA7-3 定义类 (5 分)

请补充以下代码，完成输出要求。（注意：需要提交完整代码）

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
                Scanner in = new Scanner(System.in);
                int a,b,c,d,e;
                a = in.nextInt();
                b = in.nextInt();
                c = in.nextInt();
                d = in.nextInt();
                e = in.nextInt();
                RR rr = new RR();
                double dd = rr.fun(a,b,c,d,e);
                System.out.printf("%.2f",dd);
    }
}
class RR{



}

在一行中给出5个不超过1000的正整数。

输出5个整数的平均值，保留小数点后两位。

1 2 3 4 5

3.00

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
                Scanner in = new Scanner(System.in);
                int a,b,c,d,e;
                a = in.nextInt();
                b = in.nextInt();
                c = in.nextInt();
                d = in.nextInt();
                e = in.nextInt();
                RR rr = new RR();
                double dd = rr.fun(a,b,c,d,e);
                System.out.printf("%.2f",dd);
    }
}
class RR
{
    double fun(int a,int b,int c,int d,int e)
    {
        return (a+b+c+d+e)/5.0;
    }
