I'm trying to set up an email address book on an applet. I have a list and a text field. When you enter an address into the text field and then click a button it is added to the list of addresses. However what I want to be able to do is actually write it to the file when the button is clicked so that each time you restart the applet all the contacts don't disappear.

Thanks
