public static <E> ArrayList<E> newArrayList() {
        return new ArrayList<>();
    }
Creates a <i>mutable</i>, empty {@code ArrayList} instance (for Java 6 and earlier).

<p><b>Note for Java 7 and later:</b> this method is now unnecessary and should be treated as
deprecated. Instead, use the {@code ArrayList} {@linkplain ArrayList#ArrayList() constructor}
directly, taking advantage of the new <a href="http://goo.gl/iz2Wi">"diamond" syntax</a>.
