MS Access connectivity in java

Question

I am writing a program in java for flashcards.I have an init class which launches the main JFrame. From there I have buttons to access frames to do tasks like add cards, study and help.I have written the AddCards class for adding cards.In this I am trying to connect to an MS Acess database to store cards in it but my programs returns "error". I am not able to find the error.Please help me to point it out.I am wrirting my code in NetBeans.My code for AddCards:

  package fc;
import javax.swing.*;
import java.awt.event.*;
import java.sql.Connection;
import java.sql.*;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.logging.Level;
import java.util.logging.Logger;

public class AddCards  implements ActionListener
{
    JFrame f1=new JFrame("Add Cards");
    JLabel l1=new JLabel("Enter question");
    JLabel l2=new JLabel("Enter answer");
    JTextField t1=new JTextField();
    JTextField t2=new JTextField();
    JButton b1=new JButton("ADD");
    JButton b2=new JButton("CLEAR");
    String ques,ans;
    Statement st;


 AddCards() throws SQLException
 {
    f1.setSize(600,500);
    f1.setLayout(null);
    f1.add(l1);
    f1.add(l2);
    f1.add(t1);
    f1.add(t2);
    f1.add(b1);
    f1.add(b2);
    l1.setBounds(70, 60, 100,20);
    t1.setBounds(170, 60, 300, 100);
    l2.setBounds(70, 200, 100,20);
    t2.setBounds(170, 200, 300, 100);
    b1.setBounds(200, 350, 100, 30);
    b2.setBounds(350, 350, 100, 30);
    f1.setVisible(true);
    b1.addActionListener(this);
    b2.addActionListener(this);
    f1.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
 }


    public void actionPerformed(ActionEvent e) 
    {
        if(e.getSource()==b1)
        {
            Connection con=null;
            Statement st=null;

            try 
            {
                Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               con=DriverManager.getConnection("jdbc:odbc:fc");

                ques=t1.getText();
                ans=t2.getText();
                String addRow="INSERT INTO data(ques,ans) values('"+ques+"','"+ans+")";    
                st.executeUpdate(addRow);
                con.close();
            } catch (ClassNotFoundException ex) {
                Logger.getLogger(AddCards.class.getName()).log(Level.SEVERE, null, ex);
            }
                catch (SQLException ex) 
                {
                    System.out.println("Error");
                }
        } 
        if(e.getSource()==b2)
        {
            t1.setText(" ");
            t2.setText(" ");
        }

    }
   }

The whole error which is generated is as follows after using stack trace:
