Lambda.sum介绍

[英]Sums the items in the given iterable of Numbers or the iterable itself if it actually is already a single number. Actually it handles also Maps, Arrays and Iterator by collecting their values. Note that this method accepts an Object in order to be used in conjunction with the Lambda#forEach(Iterable).
[中]求给定iterable数或iterable本身（如果它实际上已经是单个数）中的项的和。实际上，它还通过收集映射、数组和迭代器的值来处理它们。请注意，此方法接受一个对象，以便与Lambda#forEach（Iterable）一起使用。

代码示例

/**
 * Sums the property values of the items in this iterable defined by the given argument.
 * @param argument An argument defined using the {@link Lambda#on(Class)} method
 * @return The sum of the property values extracted from all the items in the given iterable
 */
public <A> A sum(A argument) {
  return Lambda.sum(getInner(), argument);
}
