    Default Java arraylist question

    This is a question on my homework, can anyone help me understand what it saying ? Thanks
    "Suppose that you have an ArrayList and that it contains String objects. Which declaration of the ArrayList requires that objects retrieved using the get method be cast to Strings before calling a String method?"

    If you must cast to a String to use it as a String, then it must be a declaration that does not return a String object "as a String"

    I'm wondering...

    That question would make a lot more sense if it asked how to declare an ArrayList so that things returned by get() do not have to be cast. (angle brackets)

    I get the impression that the multiple choice answers were left out
