Question

所以我之前提出了一个问题here，其中数组中的数字应该加在一起直到12的长度。

现在，我将如何添加其余数字，让我们说

double[] addMe = {147.04, 147.66, 148.27, 148.89, 149.51, 150.13, 150.76, 151.39, 152.02, 152.65, 153.29, 153.29, 
                10, 20 ,30,40,50,60,70,80,90,100,110,120, 10,20};

从上面我得到了答案

1804.9
780.0
1804.9

但它错过了最后两个数字10 and 20，如果计数不等于12，我将如何添加它们？

感谢。

Answer 1

修改这么多，你要添加所有数字，只是你不打印最后一笔，如果元素少于12

 double sum=0.0;
for(int i=0;i<addMe.length;i++)
{
  if(i%12==0 && i!=0)
  {
    System.out.println(sum);
    sum=0;
  }

  sum +=addMe[i];
}
System.out.println(sum);//Just add this outside the loop

Answer 2

试试这个:(如果你需要在循环中打印sum，否则@ L-X的上述答案是更好的解决方案。）

double sum=0.0;
for(int i=0;i<addMe.length;i++)
{
  if(i%12==0 && i!=0)
  {
    System.out.println(sum);
    sum=0;
  }    
  sum +=addMe[i];
  if(i==addMe.length-1)
      System.out.println(sum);
}

Answer 3

你必须将它打印出循环，因为它在被平均除以12之前变为空，它不能成功打印，这就是你在循环之外添加print语句的原因，所以当它结束了，它将打印剩余的总和。

class Sum {
    public static void main(String[] arguments) {
        double[] addMe = {
            147.04, 147.66, 148.27, 148.89, 149.51, 150.13, 150.76, 151.39, 152.02, 152.65, 153.29, 153.29,
            10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 10, 20
        };
        double sum = 0.0;
        double remainder = 0.0;

        for (int i = 0; i < addMe.length; i++) {
            if (i >= (addMe.length - addMe.length / 12)) {
                remainder = remainder + addMe[i];
            }
            if (i % 12 == 0 && i != 0) {
                System.out.println(sum);
                sum = 0;
            }

            sum += addMe[i];
        }
