The above code performs the same average as before, but also computes the maximum, minimum, and count of the elements.There’s also summarizingLong and summarizingDouble.Equivalently, you can map your stream to a primitive type and then call summaryStatistics(). For example:1 IntSummaryStatistics ...

If you do allocate objects as part of the benchmark be careful to size the heap as to minimize the impact of GC and gather enough samples so that you get a fair average for how much time is spent in GC. There are even more subtle traps with benchmarking. What if the work inside ...

SQL 中类似 sum()、avg() 或者 count() 的聚集函数,实际上就是reduce 操作,因为它们接收多个值并返回一个值。流 API 定义的 reduceh() 函数可以接受 lambda 表达式,并对所有值进行合并。IntStream 这样的类有类似 average()、count()、sum() 的内建方法来做 reduce 操作,也有mapToLong()、mapToDouble()...
