Pass a variable number into an Action method from an array of buttons

Question

Hello,
I have created an array of buttons like so:
                   private javax.swing.JButton[] barray = new JButton[8];
javax.swing.ActionMap actionMap = org.jdesktop.application.Application.getInstance(K8055_Card_Control.JavaElectrodeSwitches1App.class).getContext().getActionMap(JavaElectrodeSwitches1View.class, this);
             for (int i=0;i<8;i++)    // Create Output Check Boxes
          barray[i] = new JButton();
                        barray.setAction(actionMap.get("ButtonPressed"));
          barray[i].setName("Outbox"+ String.valueOf(i+1));
          barray[i].setText("Electrode " + String.valueOf(i+1));
BoxLayout layout = new BoxLayout(jPanel1,BoxLayout.PAGE_AXIS);
barray[i].setAlignmentX(JCheckBox.CENTER_ALIGNMENT) ;
jPanel1.setLayout(layout);
jPanel1.add(barray[i]);
When a button is pressed it calls the method ButtonPressed()@Action
public void ButtonPressed()
// button pressed code here
My problem is that once the button has been pressed I don't know how to find out which button called the method. Each button operates a different switch.
I tried testing barray.isSelected(); however the ButtonPressed() method is only called once the button has released and is no longer selected.
Any ideas?
Thanks,

Actually the answer to both of these questions is ActionEvent
do for instance:
JButton b = new JButton("test");
JButon b2 = new JButton("test2");
ActionListener al = new ActionListener() {
public void actionPerformed(ActionEvent ae) {
  Object src = ae.getSource();
  String cmd = ae.getActionCommand();
  if (src == b) { //won't work unless you make b final
  //or
  if ("test".equals(cmd)) {
b.addActionListener(al);
b2.addActionListener(al);
