Lambda.index介绍

[英]Indexes the objects in the given iterable based on the value of their argument. 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]根据给定iterable中的对象的参数值对其进行索引。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。
