Toggle button problem..really urgent

Question

hi there.. i have a problem with my code and i hope someone can help me as i have a dateline to meet for my programme..
i have a set of 10 toggle buttons with 1 single actionlistener..
here is the code
p3=new JPanel();
b1=new JPanel();
ActionListener listener1 = new b1();
for (int i=1; i<=10;i++)
JToggleButton button1 = new JToggleButton(("A"+i));
button1.addActionListener(listener1)
b1.add(button1);
p3.add(b1);
whenever the user activates a button, a textarea below will show the name of the button..
for example.. if user clicks on A3.. it will appear A3 below..
this is my code below of wat i have done..
public class b1 implements ActionListener
public void actionPerformed(ActionEvent e)
Object source = e.getSource();
textarea1.append(((JToggleButton) e.getSource()).getText()+",");
my problem is this.. if the user were to deactivate the button,the textarea below will not show anything..
for example, if user click on A4, it should appear A4 in the textarea and when user click on A4 again, the textarea should not show A4 again.
and if user click on 2 buttons example A1 and A5
textarea should show A1, A5
and if user click on A1 again, the textarea should juz show A5 and A1 should not be there.
any help would be greatly appreciated..=)

Answer 1

i created 2 sets of buttons like this..
     //Buttons that Starts with A
     b1 = new JPanel();
JToggleButton[] buttons1 = new JToggleButton[11];     ToggleButtonListener1 listener1 = new ToggleButtonListener1(buttons1);
          for(int i=1; i<buttons1.length; i++)
          buttons1[i] = new JToggleButton("A" + i);
               buttons1.addActionListener(listener1);
          b1.add(buttons1[i]);
          p3.add(b1);
     //Buttons that Starts With B
          b2 = new JPanel();
     JToggleButton[] buttons2 = new JToggleButton[11];
     ToggleButtonListener1 listener2 = new ToggleButtonListener1(buttons2);
          for(int i=1; i<buttons2.length; i++)
          buttons2[i] = new JToggleButton("B" + i);
          buttons2[i].addActionListener(listener2);
               b2.add(buttons2[i]);
               p3.add(b2);
i bind these 2 groups of buttons in a single actionlistener like this
class ToggleButtonListener1 implements ActionListener
     private JToggleButton[] array;
     public ToggleButtonListener1(JToggleButton[] array)
          this.array = array;
     public void actionPerformed(ActionEvent e)
          ta1.setText("");
          for(int i=1; i<array.length; i++)
          if(array[i].isSelected())
     ta1.append(array[i].getText() + ",");
          continue;
the problem i have now is that the 2 sets of buttons are not displayed on the textarea..
for example if user clicks on A1, the textarea should appear A1 and if user clicks on B1, the textarea should display both A1 and B1.. how do i do that..?
