Answer 1

    public static void main(String[] args)throws Exception {
        System.out.println(test(1, 5));
    }

    public static String test(int start, int end){
        int sum = 0;
        int product = 1;
        for (int a = start; a <= end; a++){
            sum += a;
            product *= a;
        }
        return "累加和为：" + sum + ", 累乘积为：" +  product;
    }
