按字母顺序基于其成员项的"toString"值对Java Collection进行排序

List<String> list = new ArrayList<>();
list.add("apple");
list.add("banana");
list.add("orange");

Collections.sort(list);

String[] array = {"apple", "banana", "orange"};
Arrays.sort(array);

List<String> list = new ArrayList<>();
list.add("apple");
list.add("banana");
list.add("orange");

Collections.sort(list, new Comparator<String>() {
    @Override
    public int compare(String o1, String o2) {
        return o2.length() - o1.length();
    }
});
