Funny, because it's copypasted from AC solution without imports and class boilerplate.
If you need - I can provide you with full copypaste so you can "just copypaste" and execute.
Thank you for your helpful comment.
I can't find the imports.
Actually the problem is with the parsing of the input as mentioned previously. Even a simple loop had trouble.
It seems "hit and miss" with this website.
Speaking of learning concepts, if I wanted to use Maps without Stream, what are the steps I would use for that? Specifically, from the half-dozen websites I researched, but it seems like I will have to manually place strings into the maps; is this correct?
Will operation time be O(n + q + hash_constant), then?
This is one of my first posts; sorry if this is a stupid question/formatted badly.

amazing nobody noticed it didn't work.

Just in case, here is version with boilerplate. Java8, copypaste, ..., profit!
import java.io.*; import java.util.*; import java.util.stream.*; public class Solution { // the code from above public static void main(String[] args) { Scanner in = new Scanner(System.in); List<String> strings = IntStream.range(0, in.nextInt()).mapToObj(i -> in.next()).collect(Collectors.toList()); IntStream.range(0, in.nextInt()).mapToObj(i -> in.next()).mapToLong(q -> strings.stream().filter(q::equals).count()).forEach(System.out::println); } // }why so negative? this isn't a website that offers solutions to problems, but a place for people to learn.
Using stream is inefficient
