Java 8：如何从Stream的索引处获取元素

Question

我有一个流，我需要在该流的索引处获取元素基本上，是基于元素的索引（如List list.get(index)

Answer 1

There is a skip method that abandons access to first N elements https://docs.oracle.com/javase/8/docs/api/java/util/stream/Stream.html#skip-long-

After that you can use limit(1) and you have just one element at specified index.

EDIT: After @Holger answer there's also a possibility to call

stream().skip(index).findFirst()
