Question

我有这些代码行：

Locale[] cosas = Locale.getAvailableLocales();

for (int i = 0; i < cosas.length; i++) {
    log.info(cosas[i]);
}

我获得此列表：

例如，对于西班牙国家/地区，该列表包含两个区域设置：es_ES和ca_ES，当然，这与西班牙语不同。

然后，我的问题是，我怎么知道一个国家默认哪种语言？可以仅通过语言构造语言环境，但我需要通过该方法的参数传递国家，现在我有这个代码默认分配语言：

if (language.equals("")) {
    switch (country) {
        case "CN":
            language = "zh";
            break;
        case "ES":
            language = "es";
            break;
        case "US":
            language = "en";
            break;
        case "JP":
            language = "ja";
            break;
        default:
            country = "";
            break;
        }
    }

if (language.equals("") && country.equals("")) {
    newLocale = new Locale("es", "ES");
} else {
    newLocale = new Locale(language, country);
}

RESOURCE_BUNDLE = ResourceBundle.getBundle(BUNDLE_NAME, newLocale);

但我需要为更多语言扩展此开关。因此，我更倾向于为一个国家/地区默认分配语言。

我在这个link上找到了一个解决方案，但是我尝试了它并且它不对（例如，对于西班牙，它返回默认的ca-ES，而不是）。有人认为通过代码获取国家真的有可能吗？任何的想法？非常感谢你。

Answer 1

它必须是java吗？我在c ++中创建了一个你可能觉得有用的小exe：KyaaLocale，你可以根据需要自定义它，添加更多if/then/else或你需要的任何东西。

Answer 2

您可以获取以下语言环境的语言：

String lang = Locale.getDefault().getISO3Language();

您还可以获取该地区的国家/地区：

String country = Locale.getDefault().getISO3Country();

许多国家/地区都使用多种语言。例如，有加拿大法语和加拿大英语语言环境。

任何国家/地区都没有真正的“默认”语言。 JVM将使用其所在机器的默认本地，但也可以使用-Duser.country -Duser.language变量设置语言和国家/地区。

您还可以使用国家/地区和语言的任意组合以编程方式更改默认语言环境。例如，这有效：

    Locale l = new Locale("Ca", "Cyrl");
    Locale.setDefault(l);

Answer 3

在我看来，默认语言不存在的立场是很愚蠢的。几乎每个国家都使用官方或事实上的主导语言或本国语言。

幸运的是，使用一种以上语言的国家/地区的数量非常少（至少从我的JVM语言环境列表中可以看出），并且我们可以轻松确定所需的所有数据。因此，我们可以手动指定此信息。以下是我的（主观）排名。在某些情况下必须格外小心，例如塞尔维亚语，因为西里尔文用于官方通讯，但更多的人可以阅读拉丁文。因此，在某些情况下，这取决于您的用例。

还请注意，语言环境存储库和语言使用可能会发生变化，因此此答案可能已过时。
