ListAverageDistribution+originalList List+numberOfGroups int+groupedLists List>+ListAverageDistribution(List, int)+distribute() : List> 结尾 通过以上步骤,我们成功实现了List的平均分配。希望这篇文章能帮助你理解如何在Java中实现这一功能。如果你有任何问题或需要进一步的帮助,请随时联系我。祝你编程愉快!

虽然IntStream、DoubleStream、LongStream 都可以是求和sum 但是也仅仅只是求和,没有summing结果丰富。如果要一次性统计、求平均值什么的,summing还是非常方便的。 示例: //IntSummaryStatistics{count=10, sum=55, min=1, average=5.500000, max=10}Stream.of(1,2,3,4,5,6,7,8...
stats=numbers.stream().mapToInt((x)->x).summaryStatistics();System.out.println("列表中最大的数 :"+stats.getMax());System.out.println("列表中最小的数 :"+stats.getMin());System.out.println("所有数之和 :"+stats.getSum());System.out.println("平均数 :"+stats.getAverage());...
