1. Open file using output stream of your choice.
2. Loop through each elements in your list
3. For what ever there is in the list get the string or other native types and write to output stream.

Done.. Hope it helps..

Here's what I have, but doesn't seem to work

Code:
public static ArrayList writeAccts(ArrayList anAL, String file) { Writer output = null; try { output = new BufferedWriter( new FileWriter(file) ); output.write(anAL); } finally { if (output != null) output.close(); } return anAL; }

Code:
try { output = new BufferedWriter(new FileWriter(file)); //output.write(anAL); for (Iterator elementsInList = anAL.iterator(); elementsInList.hasNext();) { <WHAT IS IN THE LIST> element = (<WHAT IS IN THE LIST>) elementsInList.next(); output.write(<GET/MAKE String thing from your element>); } } finally { if (output != null) output.close(); }
Take care of exceptions in the code above as well ..
