问题描述
Iterator 和 Stream 似乎都是懒惰的，允许您不断将元素返回到您的内心深处.两者有什么区别?
It seems that both Iterator and Stream are lazy and allow you to keep returning elements to your heart's content. What's the difference between the two?
推荐答案
Stream memoises 和 Iterator才不是.您可以多次遍历同一个 Stream 并且每次都得到相同的结果.另一方面，迭代器只能被遍历一次.
Stream memoises and Iterator does not. You can traverse the same Stream multiple times and get the same result each time. Iterator, on the other hand, can only be traversed once.
