如何将List <T>初始化为给定大小(而不是容量)？

List<T> list = Stream.generate(null).limit(size).collect(Collectors.toList());

List<T> list = new ArrayList<>(size);
for (int i = 0; i< size; i++) {
    list.add(null);
}

List<T> list = new ArrayList<>(Arrays.asList(new T[size]));

List<T> list = new ArrayList<>(size);
for (int i = 0; i< size; i++) {
    list.add(null);
}
