Word order when giving location
When stating the location of something, do you state the location first or the subject?
To clarify what I mean, here is an example:
교실에 학생이 있어요 ~ The location (classroom) comes before the subject (student)
학생이 교실에 있어요. ~ The subject (student) comes before the location (classroom).
Which is the correct order? Thank you in advance.
