关于java：排序国家/地区列表

Sort list of countries

本问题已经有最佳答案，请猛点这里访问。

我想生成排序列表中所有国家/地区的列表。我试过这个：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17

public Map<String, String> getCountryNameCodeList() {

String[] countryCodes = Locale.getISOCountries();

Arrays.sort(countryCodes);

Map<String, String> list = new HashMap<>();

for (String countryCode : countryCodes) {

Locale obj = new Locale("", countryCode);

list.put(obj.getDisplayCountry(), obj.getCountry());
}

return list;
}

但由于某种原因，该列表未分类。坚持下去的正确方法是什么？

HashMap未排序，使用LinkedHashMap：

This implementation differs from HashMap in that it maintains a
doubly-linked list running through all of its entries. This linked
list defines the iteration ordering, which is normally the order in
which keys were inserted into the map (insertion-order).

只是改变

1	Map<String, String> list = new HashMap<>();

至：

1	Map<String, String> list = new LinkedHashMap<>();
