        Parameters:
        o - - the Object to be compared
        Returns:
        a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
        Throws:
        java.lang.ClassCastException - - if the specified object's type prevents it from being compared to this Object.
