    The index to the get() method called on line 46 was past the end of the ArrayList.
    Remember indexes range from 0 to the list length-1.
    The code should test the value of the index to be sure it does not got past the end of the list.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
