Create a program that calculates the average of different ages: ExampleGet your own Java Server // An array storing different agesintages[]={20,22,18,35,48,26,87,70};floatavg,sum=0;// Get the length of the arrayintlength=ages.length;// Loop through the elements of the arrayfor(inta...
for (int i = 1; i < array_nums.length; i++) { sum += array_nums[i]; if (array_nums[i] > max) max = array_nums[i]; else if (array_nums[i] < min) min = array_nums[i]; } // Calculate the average value of the array except for the largest and smallest values. float ...
集合(toArray(...)、collect(...),使用集合toList()、toSet()、toColletion()、groupingBy()、partitioningBy()或toMap()) 特定元素(findFirst()、findAny()) 聚合(归约)可以是以下任何一种: 算法:min(...)、max(...)、count()或sum()、average()、summaryStatistics()只针对IntStream、LongStream、Doub...

Stream<Integer>stream=Stream.of(1,2,3,4,5); 通过Stream.builder() 创建:如果我们不确定要添加多少个元素到 Stream 中,可以使用Stream.builder()创建一个 Stream.Builder 对象,并使用其add()方法来逐个添加元素,最后调用build()方法生成 Stream 对象。例如: ...
list.stream().mapToDouble(User::getHeight).sum()//和 list.stream().mapToDouble(User::getHeight).max()//最大 list.stream().mapToDouble(User::getHeight).min()//最小 list.stream().mapToDouble(User::getHeight).average()//平均值 1. List转Map id为key,apple对象为value,可以这么做: ...
