    Default Need help with write to .dat file code from textarea

    I have other part of program reading from textField which works fine. My problem is i cannot get the textArea to do the same thing:

    ind = TextArea

        private void saveActionPerformed(java.awt.event.ActionEvent evt) {
         ind.setText(""); 
     
        String text = ind.getText();
     
     
            File file = new File("C:Inventory2.dat");
     
     
                 try {
                FileOutputStream out = new FileOutputStream(file, true);
     
                String textsub = (text);
     
                out.write(textsub.getBytes());
     
                out.close();
            } catch (FileNotFoundException ex) {
            } catch (IOException ioe) {
            }
     
        }

    get the textArea to do the same thing:
    Please explain what the problem is. What does the code do or not do?
    What is written to the file?
    If you don't understand my answer, don't ignore it, ask a question.

    I bet nothing is written:
    ind.setText(""); 
    String text = ind.getText();

    PhHein thank you that fixed it. setText was erasing everything so nothing was added.
