I would like to enter a new item into a CSV file but all my items being entered are all staying on one line in the CSV file. I would like each new item to show up on a new line and I can't seem to find the code to make it work. I've tried the \n and that didn't work.

There are methods in the BufferedWriter class which can help with new lines. You are better off buffering your FileWriter with a BufferedWriter. There is an example in the BufferedWriter API. BufferedWriter has a write() method which writes a String, but I think you would do better to put all your Strings together with a StringBuilder, and call its toString() method. That is because you get better performance with fewer calls to access the file. Write one line at a time rather than one word at a time.
