推荐的方法是哪一个:

private final List<Object> list = new ArrayList<>();

public List<Object> getListView() {
    return Collections.unmodifiableList(list);
}

要么

private final List<Object> list = new ArrayList<>();
private final List<Object> listView = Collections.unmodifiableList(list);

public List<Object> getListView() {
    return listView;
}

后者节省了对象创建,但值得努力吗？
