Question

Hello everybody. I'm still facing difficulties while trying to solve

the filtering issue in a map with the stream. So basically I have a Map of tweet objects. The objects have LocalDate as attribute which I implemented for example like this: LocalDate.parse("2021-10-11"). Among with other attributes. Now my goal is to iterate through the map and filter a certain date with the method isbefore(). I can't find a way to get it work on a map. I could convert the map to an arraylist/list but it is not the part of the task. Basically I have to search for tweets that have been tweeted before a certain date and have more than 20 retweets and are sorted by popularity. Is it possible to chain all this filters in one go? Any help is greatly appreciated.
