Save data from a JTable to a file

Question

I have been working with the Camickr's example:
package tabla;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;
public class MikeToth extends JFrame
     private JTable table;
     private DefaultTableModel model;
     public MikeToth()
          String aLine ;
          Vector columnNames = new Vector();
          Vector data = new Vector();
          try
               FileInputStream fin = new FileInputStream("MikeToth.txt");
               BufferedReader br = new BufferedReader(new InputStreamReader(fin));
               // extract column names
               StringTokenizer st1 = new StringTokenizer(br.readLine(), "|");
               while( st1.hasMoreTokens() )
                    columnNames.addElement(st1.nextToken());
               // extract data
               while ((aLine = br.readLine()) != null)
                    StringTokenizer st2 = new StringTokenizer(aLine, "|");
                    Vector row = new Vector();
                    while(st2.hasMoreTokens())
                         row.addElement(st2.nextToken());
                    data.addElement( row );
               br.close();
          catch (Exception e)
               e.printStackTrace();
          //  Create table using the DefaultTableModel
          model = new DefaultTableModel(data, columnNames);
          table = new JTable(model);
          JScrollPane scrollPane = new JScrollPane( table );
          getContentPane().add( scrollPane );
          JPanel buttonPanel = new JPanel();
          getContentPane().add( buttonPanel, BorderLayout.SOUTH );
          //  Empty Row button
          JButton button1 = new JButton( "Add Empty Row" );
          buttonPanel.add( button1 );
          button1.addActionListener( new ActionListener()
               public void actionPerformed(ActionEvent e)
                    model.addRow( new Vector() );
          //  Save table to file button
          JButton button2 = new JButton( "Save Table to File" );
          buttonPanel.add( button2 );
          button2.addActionListener( new ActionListener()
               public void actionPerformed(ActionEvent e)
                    //  Finish editing the current cell before saving
                       if  ( table.isEditing() )
                         int row = table.getEditingRow();
                         int col = table.getEditingColumn();
                         table.getCellEditor(row, col).stopCellEditing();
                    int rows = table.getRowCount();
                    int columns = table.getColumnCount();
                    //  Write out the Column Headers
                    TableColumnModel header = table.getColumnModel();
                    for (int k = 0; k < columns; k++)
                         TableColumn column = header.getColumn(k);
                         String value = (String)column.getHeaderValue();
                         System.out.print( value );
                         System.out.print( "|" );
                    System.out.println();
                    //  Write out the table data
                    try{
                           DataOutputStream out2 = new DataOutputStream(
                                      new BufferedOutputStream(
                                        new FileOutputStream("Data.txt")));
                          for (int j = 0; j < rows; j++)
                                   for (int k = 0; k < columns; k++)
                                       String value = (String)table.getValueAt(j, k);
                                        System.out.print( value );
                                        System.out.print( "|" );
                                        out2.writeBytes(",");
                                        out2.writeBytes(value);
                                   out2.close();
                                   System.out.println();
                    catch(IOException ee) {
                          throw new RuntimeException(ee);
     public static void main(String[] args)
          MikeToth frame = new MikeToth();
          frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
          frame.pack();
          frame.setVisible(true);
}But i dont get good results. In the console the data are perfects: column's name in the first line, and the data of each row in different lines. But when i insert in the file the data are introduced serial in a single line. Example
In the console i get:
column1|column2
3 | 4
3 | 2
In the file i get:
3,4,3,2
Ok, my question is: can i get the data directly from the console and then introduce it in the file ( with the same format that in the console)??
Thanks for your time.

Never Mind, got it to. =)
this is how i made it work.
for (int j = 0; j < rows; j++)
                         for (int k = 0; k < columns; k++)
                              String value = (String)table.getValueAt(j, k);
                                                out.write("|");
                                                out.write( value );
                                         out.newLine();
                    }out.close();
