JTextField ActionListener Help

Question

Hallo Guys,
I have an JTextField . when the user inputs the number and clicks the InsertString button i generate that many JTextField for the user to insert some Strings.
if the user enters 10 and clicks the InsertString Button then 10 JTextFields appear. it works fine
but my problem is how to access the text entered in the different JTextFields.
i can access only the last textField
Here is the piece of code
if(cmd.equals("InsertString"))
     if(numvaluesField.getText().equals(""))
     ImageIcon icon = new ImageIcon("Images/warning_large.gif");
     JOptionPane.showConfirmDialog(null,"Please Input the Number of Values and then Press the InsertString Button","Alert",JOptionPane.DEFAULT_OPTION,JOptionPane.INFORMATION_MESSAGE,icon);
     else
          stringButton.setEnabled(false);
          deleteButton.setEnabled(true);
          Container contentPane = valueFrame.getContentPane();
          GridBagLayout gridbag = new GridBagLayout();
          sub1 = new JPanel(gridbag);
          GridBagConstraints c = new GridBagConstraints();
          GridBagConstraints d = new GridBagConstraints();
          c.anchor = GridBagConstraints.CENTER;
         c.fill = GridBagConstraints.BOTH;
         c.insets = new Insets(5, 5, 5, 5);
         c.weightx = 1.0;
         c.weighty = 1.0;
         try{
          numValue = Integer.parseInt(numvaluesField.getText());
         catch(NumberFormatException exception){};
     if(numvaluesField.equals(""))
          JOptionPane.showConfirmDialog(null,"The number of values field Cannot be NULL","Alert",JOptionPane.DEFAULT_OPTION,JOptionPane.INFORMATION_MESSAGE);
     else{
     for(int i = 1; i <= numValue ; i++)
          c.gridx = 2 ;
          c.gridy = i ;
          lengthField.setText(String.valueOf(Integer.parseInt(lengthField.getText()) + 2));
          JLabel stringLabel= new JLabel("String"+i+":");
          sub1.add(stringLabel,c);
          //stringField = new JTextField[numValue];
          stringField = new JTextField(10);
          stringField.addActionListener(this);
          stringField.setToolTipText("Enter the String name for Parameter Acquisition");
          c.gridx = 3;
          c.gridy = i;
          sub1.add(stringField,c);
          d.gridx = 1;
          d.gridy = 0;
          main.add(sub1,GridBagConstraints.RELATIVE);
          contentPane.add(main);
          valueFrame.setContentPane(contentPane);
          valueFrame.pack();
}here is the code where i access the JTextFields
for(int i = 1 ; i <= numValue1 ; i++)
     StringBuffer buff = new StringBuffer();
     buff.append(stringField.getText());     
value = messageString.createStringField(value,buff.toString());
     buff.setLength(0);
}

Hi freedomjava,
Torajirou is right you'r overwrite the reference so the only textfield available is the last one..
For simple example you just think what should be the out put of the following ?? and you should got your mistake..
         int i=0;
         i=1;
         i=100;
         System.out.println("Value of i  = "+i);You should got the last value....
