Yes I did touch Hotel.java because I am going to use the search thing to get data out of the database. Therefore I modify some parts of it. However, I am not sure if I did the correct thing or not. I just change the attributes of the hotel to match what we have but still call it hotel. Is it because I touched Hotel.java?? I will try to run it with the original one then.
