  • exactly encoding error when reading from console? can she in the formation of html? go through debugging, see what is in the variables after reading from the console - Victor

 public String getInput() { try { BufferedReader reader = new BufferedReader( new InputStreamReader (System.in)); String path = reader.readLine(); return path; } catch (IOException ex) { Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex); } return null; }

How to use: String input = getInput();

To write something to the file you can use this function.

 public void writeToFile(String pathToFile, String text) { try{ out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(pathToFile),"Cp1251")); out.write(text); out.newLine(); out.close(); } catch (IOException e){ System.out.println(e.getMessage()); } }

The first argument is the path to the file to which you need to write something.

The second argument is the text itself to be written.

  • Why should a person write to a file if he has a problem reading data from the console? You just added a wrapped BufferedWriter wrapper to its code - Victor
  • Than FileWriter not happy? - And

It is important in what encoding you read the data. Those. find out the console encoding in your operating system. Perhaps it will need to switch to another. Or, when reading data, consider it (something like Scanner in = new Scanner(System.in, "UTF-8"); ).
