If I do a system restore will I get my program back?

I made a project on eclipse for school to hand in. I edited some minor things in my program in a rush and handed it in without checking if my program still ran. Turns out it didn't, and I can't seem to find the error. I don't have time to figure it out. if I did a system restore to that point in time before I handed it in, will my project be at the same state it was, at that time?

thank you

Sorry, I know this isn't the right section but I'm new to this site and don't know where to go...
