    Well, the error message you get is very exact.
    You attempt to use the "set" method of the ArrayList class with in invalid index.
    Read the documentation for the arraylist; you can only use set on an index when the list has at least a size equal to the index + 1.
    Your array list however has a size of 0 and thus you can not use the set method with any index.

    What you want to do is probably "add" elements to the list.

    At line 48 the code called the set() method with an invalid value. See post#27 for explanation.
    If you don't understand my answer, don't ignore it, ask a question.
