java stream doesn't compile with Locale's method function, why?
-3
I've got this:
Locale locale = new Locale("en", "US", "WIN");//ok
System.out.println(locale.getLanguage());//ok
Stream<Locale> sl = Stream.of(Locale.getAvailableLocales());//ok
Map<String, List<Locale>> map = sl.collect(
Collectors.partitioningBy(l->l.getLanguage().equals("en")));//error
Compilation error: Cannot resolve method "getLanguage()".
How to fix it?

What do you thinkpartitioningBydoes? What do you think should be stored inMap<String, List<Locale>>? What would the values be in that map? Why do you think so?

See the documentation: partitioningBy returns a Collector that produces aMap<Boolean, List<T>>.

A word of advice, a lot of your recent questions have been poorly received. The thing I think is missing from a lot of them is why. You dump a piece of code with an error message, but never explain why you think that piece of code should work. Half the time, if you just asked yourself that and followed the thread, you'd be able to answer these questions yourself.

If you are trying to group the locales by language then use groupingBy instead of partitioningBy :
Stream<Locale> sl = Stream.of(Locale.getAvailableLocales());
Map<String,List<Locale>> localsPerLanguage = sl.collect(Collectors.groupingBy(Locale::getLanguage));
System.out.println(localsPerLanguage.get("fr"));
