	private static String savefile = "E://test.txt";private static void saveAsFileWriter(String content) { 	 FileWriter fwriter = null;	 try {	 fwriter = new FileWriter(savefile);	 fwriter.write(content);	 } catch (IOException ex) {	 ex.printStackTrace();	 } finally {	 try {	 fwriter.flush();	 fwriter.close();	 } catch (IOException ex) {	 ex.printStackTrace();	 }	 }	}
