File/FileWriter Stuff

//File.createNewFile() not needed when used with a FileWriter (Ps. I learned that today!)

//Method #1
private static void writeCcStart(final Short stno, final Integer invno) {
	 final String fileName = CWDefaultDirectory.getCwDefaultDirectory() + "CreditCardStart.txt";
	 final File file = new File(fileName);

		 writer.write(stno + "|" +invno);
	 } catch (IOException e) {
		LOGGER.error("Error in writing credit card start file invoice {} {}", invno, e.getMessage());
	 }
}

//Method #2
