Default Problem with a program from book

Hello. I have copied this program from one of the books (Ivor Horton's Beginning JAVA 2) and there are three mistakes which I cannot correct them. If you can give me any hint it would be very helpfull to me.

import java.awt.BorderLayout;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.JTextArea;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.Statement;
import java.sql.SQLException;

public class InteractiveSQL extends JFrame
    public static void main(String [] args)
        InteractiveSQL theApp=new InteractiveSQL("sun.jdbc.odbc.JdbcOdbcDriver","jdb c:odbc:contact","admin","rjdemo");

    public InteractiveSQL(String driver, String url, String user, String password)
        setBounds(0, 0, 400, 300);
        addWindowListener(new WindowAdapter()
            public void windowClosing(WindowEvent e)
        command.setToolTipText("Key SQL command and press Enter");
        getContentPane().add(command, BorderLayout.NORTH);
        getContentPane().add(status, BorderLayout.SOUTH);
        JMenu fileMenu= new JMenu("File");
            connection= DriverManager.getConnection(url, user, password);
            statement= connection.createStatement();
            model= new ResultsModel();
            JTable table= new JTable(model);
            resultsPane= new JScrollPane(table);
            getContentPane().add(resultsPane, BorderLayout.CENTER);
        catch(ClassNotFoundException cnfe)
        catch(SQLException sqle)

    JTextField command= new JTextField();
    JTextArea status= new JTextArea(3, 1);
    JScrollPane resultsPane;
    JMenuBar menuBar= new JMenuBar();
    JMenuItem clearQueryItem= new JMenuItem("Clear query");
    JMenuItem exitItem= new JMenuItem("Exit");
    Connection connection;
    Statement statement;
    ResultsModel model;

Thank you in Advance

Following line has mistake

Here method should be 'setAutoResizeMode' instead of 'setAutoResizeModel'

For remaining two mistakes

You have to wite class ResultsMode which exteds 'javax.swing.table.AbstractTableModel'

you can find exmaple at http://logos.cs.uic.edu/Examples%20A...ultsModel.java
