问题描述
哪种是从集合中创建流的最佳方法:
Which is the best way to create a stream out of a collection:
final Collection<String> entities = someService.getArrayList();
-
entities.stream();
Stream.of(entities);
推荐答案
第二个没有按照您认为的做！它不会不为您提供包含集合元素的信息流；相反，它将为您提供带有单个元素的流，该元素是集合本身(而不是其元素).
The second one does not do what you think it does! It does not give you a stream with the elements of the collection; instead, it will give you a stream with a single element, which is the collection itself (not its elements).
如果需要具有包含集合元素的流，则必须使用entities.stream().
If you need to have a stream containing the elements of the collection, then you must use entities.stream().
