    Default Re: ArrayList

    This sounds like a bad idea. What purpose would you have for a List that contains Chair, Spoon, Dog etc? On the other hand if the goal was to have a List of randomly generated Fiat, Ford, Audi, BMW etc objects then perhaps those classes should all extend a super class and you make the type of your List that super class:
    ArrayList<CarMake> cars = new ArrayList<CarMake>();
    ;
