    Default Quick question

    What is the difference between

    ArrayList myList = new ArrayList();

    and

    List myList = new ArrayList();

    And why(if it is) is one more beneficial than the other?

    Im really confused because it seems to me that they both do exactly the same thing

    Thanks in advance~

    The first myList can use all the methods of the ArrayList class
    The second myList can only use the methods of the List class.
