It seems to be an issue about file paths.
I see that you have changed the package name so this could be the reason.
I would recomment to change the file paths to relative paths.
For example:
String input = "c:\\your_directory\\your_inputfile.txt";
String output = "c:\\your_directory\\your_outputfile.txt";
Then it should work.
