I am willing to create a list of options to test something.

I was doing:

ArrayList<String> places = new ArrayList<String>();
places.add("Buenos Aires");
places.add("Córdoba");
places.add("La Plata");

I refactor the code doing:

ArrayList<String> places = new ArrayList<String>(Arrays.asList("Buenos Aires", "Córdoba", "La Plata"));

Is there a better way of doing this?

Thanks for reading!
