May I know why did you say I am comparing subject_name to an integer ?

I am trying to get both tutor_id and subject_name from the same table based on the no of ? in subjectName as per parameterValues.

Again, you need to send messages to the mailing, not me personally.
That said you might want to first figure out what:
ps2.setInt(1, tutor_id); 

is supposed to accomplish in your code.
