It would make it easier to follow the code if your indentation was correct, but:

Why are you creating the file and then deleting it?

But that's not what that code is doing.

What happens if you remove the createNewFile call?
It doesn't seem to be adding anything.

But the FileWriter creates the file.
It doesn't need you to call createNew File.
If it can't create the file then it will throw an IOException.

If that is the issue then all you are doing is covering up another problem.
