Set – это куча ненумерованных объектов, Map — это множество пар «ключ-значение». Они хоть и похожи, но что дозволено делать с Map, не получится сделать с Set. В The subclass's set(int, E), get(int), add(int, E), remove(int), addAll(int, Collection) and removeRange(int, int) methods all delegate to the corresponding methods on the backing abstract list, after bounds-checking the index and adjusting for the offset. The addAll(Collection c) method merely returns addAll… ArrayList list = new ArrayList<>(); list.add("elephant"); System.out.println(list); // Add all elements to the ArrayList from an array.
