In this section of the code [ addToList(bList, ???); ] an audiofile is added, this file will come from a checkbox being checked. How would this code add the audiofile to the blist in the following piece of code (addToList(bList, ???);) if I named the checkboxs 2sec-12sec.   I got this code from objects.

addToList(bList, ???);


public class MyListener implements ActionListener {

    private List aList = new ArrayList();
    private List bList = new ArrayList();

    public MyListener() {
    }

    public void addButton(JButton theButtonToAdd) {
       theButtonToAdd.addActionListener(this);  // Listen for the button to be pressed
    }

    public void actionPerformed(ActionEvent e) {
       JButton button = (JButton)e.getSource();
       String command = button.getActionCommand();
       addToList(aList, command);
       addToList(bList, ???);
    }

    private static List list, String file) {
       if (list.contains(file))
       {
          list.remove(file);
       }
       else
       {
          list.add(file);
       }
    }

    public List getAList() { return aList; }
    public List getBList() { return bList; }

}

the following will allow you to use the class with both JButton's and JCheckBox's.

public class MyListener implements ActionListener {

    private List aList = new ArrayList();
    private List bList = new ArrayList();

    public MyListener() {
    }

    public void addButton(AbstractButton theButtonToAdd) {
       theButtonToAdd.addActionListener(this);  // Listen for the button to be pressed
    }

    public void actionPerformed(ActionEvent e) {
       AbstractButton button = (AbstractButton)e.getSource();
       String command = button.getActionCommand();
       addToList(aList, command);
       addToList(bList, ???);
    }
