    }
    
    public static void main(String[] args)
    {
        //Make an array list of Strings
        //add the strings "cat", "dog", "elephant", "ferret", and "goat" to it
        //print the list 
        //Replace all of the entries in the list with
        //upper-case versions.
        //print the list
        //empty the list
        //print the list
    }
}
