[Java] - JTextArea Problem

Sean^DCT4

Hi all,

I was writing a GUI in Java and I wanted to have a JTextArea that has multiple lines of text and a JButton that when clicked wrote the contents of the JTextArea to a .txt file.

Here's my code:

private void jButton4ActionPerformed(java.awt.event.ActionEvent evt) {                                         
        JFileChooser jfc = new JFileChooser();
        String tStore = jTextArea1.getText();
        int x = jTextArea1.getLineCount();
        System.out.println(x);

        if (evt.getSource() == jButton4) {
            int returnVal = jfc.showSaveDialog(HTMLStripperMain.this);

            if (returnVal == JFileChooser.APPROVE_OPTION) {
                File file = jfc.getSelectedFile();
                String fileName = file.getAbsolutePath();
                fileName = fileName.concat(".txt");
                System.out.println("Saving: " + file.getName() + ".");
                System.out.println(fileName);
                int totalLines = jTextArea1.getLineCount();

                try {
                    BufferedWriter out = new BufferedWriter(new FileWriter(fileName, true));
                    for (int i = 0; i < totalLines; i++) {
                        try {
                            int start = jTextArea1.getLineStartOffset(i);
                            int end = jTextArea1.getLineEndOffset(i);
                            String line = tStore.substring(start, end);
                            out.write(line);
                            out.newLine();
                            out.close(); //close stream for writing
                            System.out.println("line = " + line);
                            System.out.println("i = " + i);
                        } catch (javax.swing.text.BadLocationException ble) {
                            ble.getMessage();       
                            ble.printStackTrace();  
                        } catch (IOException ioe) {
                            ioe.getMessage();
                            ioe.printStackTrace();
                        }


                    }
                } catch (IOException e) {
                    e.printStackTrace();   
                    e.getMessage();       
                }

                JOptionPane.showMessageDialog(this, "Save successful: " + fileName, "Saved .txt file", 2, null);

            } else {
                System.out.println("Save command cancelled by user.");
            }
        }
    }                

and here's my error:

EDIT:
Forgot to mention: If the JTextArea has the following:

asdasdad
cvbcvbcv
adgdfgdf

It will write the first line to the txt file and then throw the IOException error. i.e. it will write "asdasdad" to the text file and that's it.
So close yet so far..

I haven't run it but you appear to be closing the output stream in your for loop - without running it I can't be sure but it seems to be your problem.

out.close(); //close stream for writing

thanks, I got it earlier on.
I thought it was the out.newLine() or the "\n" I was trying.. I forgot I was still inside the for-loop.

I think I need some time off

thanks again
