DefaultTableModel help

[charlie mills]

I'm trying to read in data from a file and then display the data in a table.

I've just managed to read the data into a string. I printed the data out in the command line just to check it was working and it was.
Then I tried to add the DefaultTableModel, but I got a it confused as to what code should be in which method and I can't get my program to compile now.
I think the code is all right, I've just got bits of it in the wrong place.

import javax.swing.*;
import java.awt.*;
import javax.swing.table.*;
import java.io.*;
import java.util.*;

class AddressBook extends JFrame
{
    DefaultTableModel contactsTable;

    String line = new String();

    public readLine() throws IOException
    {
        BufferedReader file_in = new BufferedReader (new FileReader("AddressBook.buab"));
        
         ArrayList<String> addresses = new ArrayList<String>();
         while (true)
         {
             line = file_in.readLine();
             if (line == null)
                 break;
             addresses.add(line);
             System.out.println(line);
         }
    }

   public AddressBook()
    {
        this.setSize(new Dimension(640, 480));
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.setLayout(new GridBagLayout());

        GridBagConstraints c = new GridBagConstraints(0,0,1,1,0.01,1.0,
                 GridBagConstraints.NORTH, GridBagConstraints.NONE,
                 new Insets(0,0,0,0),0,0);
        JButton search = new JButton("Search");
        this.add(search, c);

        c.gridx++;
        JButton add = new JButton("Add");   
        this.add(add, c);

        c.gridx++;
        JButton importData = new JButton("Import");
        this.add(importData, c);

        c.gridx++;
        JButton export = new JButton("Export");
        this.add(export, c);

        c.gridx++;
        JButton delete = new JButton("Delete");
        this.add(delete, c);

        c.fill = GridBagConstraints.BOTH;
	c.gridx = 0;
        c.gridy = 1;
        c.gridwidth = 5;
        this.contactsTable = new DefaultTableModel (line, new String[] {"Surname", "First Name", "Home Phone Number", "Mobile number", "Address"});
        JTable table = new JTable(this.contactsTable);
        JScrollPane scrollpane = new JScrollPane(table, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
        this.add(scrollpane, c);

        this.setVisible(true);
    }

    public static void main(String[] args) throws IOException
    {
        new AddressBook();
    }
}

The error messages will tell you exactly what's wrong. I think that rather than someone giving you the solution, you would be best served in the long run to try to use the information given in these messages (and the Java API) to try to solve your problem. Then if you find some of the error messages confusing and hit a road block, come on back here, post the error message(s) and your questions and we'll explain it to you.

Best of luck!

So much for listening to the advice I gave you in your previous post. Sometimes I wonder why I even bother spending the time.
