import text file to JTable by using JFilechooser

AmrutaSriram

If Anyone Knows , can you please help me how to import the text file to JTable by using JFilechooser ?

Even the text file contains the specific charecters line length

eg: idUsernamePasswordEmailAgeGender ( ID = 2 Chars, Username = 10 chars ( if username not having 10 chars means, it include space for that, password = 5 chars, email = 5 chars, Age = 2 chars, Gender = 1 chars)

       String[] defaultCols = {"Id", "Username", "Password", "email","Name","Age","Gender"};

       DefaultTableModel model = new DefaultTableModel(defaultCols, 0);

       JTable table = new JTable(model);

       JButton button = createButton(table);

       JFrame frame = new JFrame();

       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

       frame.add( new JScrollPane(table));

       frame.add(button, BorderLayout.SOUTH);

       frame.pack();

       frame.setLocationByPlatform(true);

       frame.setVisible(true);

   }

   private JButton createButton(final JTable table) {

       JButton button = new JButton("Get File");

       button.addActionListener(new ActionListener() {

           public void actionPerformed(ActionEvent e) {

               JFileChooser chooser = new JFileChooser();

               int result = chooser.showOpenDialog(table);

               if (result == JFileChooser.APPROVE_OPTION) {

                   File file = chooser.getSelectedFile();

                   DefaultTableModel model = createModel(file);

                   table.setModel(model);

               }

           }

       });

       return button;

   }

   private DefaultTableModel createModel(File file) {

       DefaultTableModel model = null;

       try {

           BufferedReader txtReader = new BufferedReader(

                   new FileReader(file));

           String header = txtReader.readLine();

           model = new DefaultTableModel(header.split("\\s+"), 0);

           String line;

           while ((line = txtReader.readLine()) != null) {

               model.addRow(line.split("\\s+"));

           }

       } catch (IOException ex) {

           ex.printStackTrace();

       }

       return model;

   }

   public static void main(String[] args) {

       SwingUtilities.invokeLater(new Runnable() {

           public void run() {

               new TestTable5();

           }
