Arrays 需要帮助缩短我的java代码（netbeans）

我有一个问题，缩短我的代码。 样本输出： 您将输入多少个整数？ 4. 输入4个整数，每行一个： 2. 1. 1. 2. 总数是6。 有关数字如下： 2，占总额的33.33%。 1，占总额的16.67%。 1，占总额的16.67%。 2，占总额的33.33%

示例输出应该是这样的。我已经完成并执行了任务，但我的代码很长

我认为这可能会对您有所帮助，但我想这是您的家庭作业，因此最好理解代码并尝试自己完成

public static void main(String[] args)
{
    Scanner scan = new Scanner (System.in);
    ArrayList<Integer> list = new ArrayList<>();

    System.out.print("How many integers you will enter: ");
    int howMany = scan.nextInt();

    double sum = 0;
    int number;

    for(int i = 0; i < howMany; i++)
    {
        System.out.println("Enter " + (i+1)  + ". number:  ");
        number = scan.nextInt();
        list.add(number);   
        sum += list.get(i);
    }
    System.out.println("Sum is : " + sum);

    for(int numbers : list)
    {
        System.out.println("Number is " + numbers + " which is " + (numbers/sum) + " of the sum");
    }
}

publicstaticvoidmain（字符串[]args）
{
扫描仪扫描=新扫描仪（System.in）；
ArrayList=新建ArrayList（）；
System.out.print（“您将输入多少个整数：”）；
int howMany=scan.nextInt（）；
双和=0；
整数；
for（int i=0；i<多少；i++）
{
System.out.println（“输入”+（i+1）+”。数字：”；
number=scan.nextInt（）；
列表。添加（编号）；
sum+=list.get（i）；
}
System.out.println（“总和为：“+Sum”）；
用于（整数编号：列表）
{
System.out.println（“数字是“+numbers+”，它是总和的“+（数字/总和）+”）；
}
}

您应该阅读有关数组/列表和循环的内容。这样做，您就可以缩短自己的代码。
