Java中for循环求平均值

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        float sum = 0;
        for (int i = 0; i < 5; i++) {
            System.out.print("请输入周"+(i+1)+"周的学习时间：");
            sum += in.nextInt();
        }
        System.out.println("周一至周五每日平均学习时间是:"+sum/5+"小时");
    }

Scanner in= new Scanner(System.in);
double sum = 0;
for (int i = 1; i <= 5; i++)
{
    System.out.print("请输入第" + (i) + "周的学习时间:");
    int score =in.nextInt();
    sum = sum + score;
}
System.out.println("周一至周五每日平均学习时间是：" + sum / 5+"小时");
