public static void append(){


BufferedWriter bw = null;





try {


bw = new BufferedWriter(new FileWriter("checkbook.txt", true));


bw.write(new Date() + "");


bw.newLine();


bw.flush();


} catch (IOException ioe) {


ioe.printStackTrace();


} finally {


if (bw != null)

bw.close();


} catch (IOException ioe2) {





}
