Look at the following method. Right now it does not even compile. How would you fix it$?$ Keep these thoughts in mind.

If a programmer calls the method, and the method cannot create the output file, the method should notify the caller that a problem occurred. Look at the Printwriter constructor to see how it handles this situation.

If an error occurs when writing to the file, you'll need to make sure that all of the data you've written so far has been safely saved.

See Programming Tip "Throw Early, Catch Late" in the "Exception Handling" section for some help with this.
