Adding ActionListeners to an array of buttons in an applet

I have made a game where a user must input a binary number equivalent to a decimal. User clicks on buttons that toggle between 0 and 1. This worked fine as an application in eclipse but when I tried to run as an applet it did not run correctly. Only the first button registered any events( only the first action listener was added?) How can I get this to work? Any helpful suggestions welcomed!

for(int i = 0; i < buttons.length; i++) {
    buttons[i] = new JButton("0");
    buttons[i].setActionCommand("0");
    buttons[i].setEnabled(true);
    bpanel.add(buttons[i]);
}                                 

    for (int i = 0; i<size;){
    buttons[i].addActionListener(   
    new ActionListener(){
           public void actionPerformed(ActionEvent e) {
           String choice = (String) e.getActionCommand();

You have set same action command on all your buttons:
buttons[i].setActionCommand("0");

and here this particular code:
String choice = (String) e.getActionCommand(); returns 0 for every button click

Try setting different action commands for each button

All your buttons have the same text and the same action command.

You should probably change the first lines in the first loop to something like:

buttons[i] = new JButton(i + "");
buttons[i].setActionCommand(i + "");
