If I have a List>, how can I turn that into a List that contains all the objects in the same iteration order by using the features of Java 8? Answer You can use flatMap to flatten the internal lists (after converting them to Streams) into a single Stream, and then collect the result into a list:List> list = ...List flat = list.stream() .flatMap(List::stream) .collect(Collectors.toList()); No comments: Post a Comment Newer Post Older Post Home Subscribe to: Post Comments (Atom) plot explanation - Why did Peaches' mom hang on the tree? - Movies & TV In the middle of the movie Ice Age: Continental Drift Peaches' mom asked Peaches to go to sleep.
