hello! here is what i want from santa...
i have a hashmap with string-boolean as key/value pairs.
sth like:
"fact1"-true
"fact2"-false
"fact3"-false
"fact4"-true
etc...
Is there any way that i can get in any kind of array or collection the entries/keys/"facts" with value, say, only false??

Only by iterating through the map and collecting the entries with the given value into a list. Easy enough to do!

Have you come across BitSets? Would that help?
