java.text.ParseException : Unparseable date (German, 乌克兰语)

Question

我需要将日期解析为 11 种不同的语言。到目前为止，只有两个给我带来麻烦:德语和乌克兰语。

package com.example;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;

public class TestDate {

    private static SimpleDateFormat DATE_SDF;

    public static void main(String[] args) {
        // German
        DATE_SDF = new SimpleDateFormat("dd MMM yyyy", Locale.GERMAN);
        DATE_SDF.setLenient(false);
        String[] germanDate = {"11 Jan 1970", "11 Feb 1970", "11 Mär 1970", 
                "11 Apr 1970", "11 Mai 1970", "11 Jun 1970",
                "11 Jul 1970", "11 Aug 1970", "11 Sep 1970", 
                "11 Okt 1970", "11 Nov 1970", "11 Dez 1970"};
        for (String germanDateIterator: germanDate) {
            try {
                Date parsedGermanDate = DATE_SDF.parse(germanDateIterator);
                System.out.println("parsedGermanDate:" + parsedGermanDate);
            } catch (ParseException e) {
                e.printStackTrace();
            }
        }

        // Ukrainian
        DATE_SDF = new SimpleDateFormat("dd MMM yyyy", new Locale("uk"));
        DATE_SDF.setLenient(false);
        String[] ukDate = {"11 Січ 1970", "11 Лют 1970", "11 Бер 1970", 
                "11 Кві 1970", "11 Тра 1970", "11 Чер 1970", 
                "11 Лип 1970", "11 Сер 1970", "11 Вер 1970", 
                "11 Жов 1970", "11 Лис 1970", "11 Гру 1970"};
        for (String ukDateIterator: ukDate) {
            try {
                Date parsedUkDate = DATE_SDF.parse(ukDateIterator);
                System.out.println("parsedUkrainianDate:" + parsedUkDate);
            } catch (ParseException e) {
                e.printStackTrace();
            }
        }
    }
}

这个测试的输出是:

parsedGermanDate:Sun Jan 11 00:00:00 MST 1970
parsedGermanDate:Wed Feb 11 00:00:00 MST 1970
java.text.ParseException: Unparseable date: "11 Mär 1970"

java.text.ParseException: Unparseable date: "11 Гру 1970"
    at java.text.DateFormat.parse(Unknown Source)
    at com.example.TestDate.main(TestDate.java:32)

为什么其中一些起作用而另一些不起作用？我该怎么做才能让他们全部工作？我正在使用 Java 版本“1.7.0_11”。

我调整了 assylias 提供的代码以适合我的原始示例:

package com.example;

import java.io.IOException;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import java.util.List;
import java.util.Locale;

public class TestDate {

    public static void main(String[] args) throws IOException {
        List<Locale> localeList = new ArrayList<Locale>();
        localeList.add(new Locale("de"));
        localeList.add(new Locale("en"));
        localeList.add(new Locale("es"));
        localeList.add(new Locale("fr"));
        localeList.add(new Locale("it"));
        localeList.add(new Locale("pt"));
        localeList.add(new Locale("ru"));
        localeList.add(new Locale("uk"));
        localeList.add(new Locale("ko"));
        localeList.add(new Locale("ja"));
        localeList.add(new Locale("zh"));
        for (Locale currentLocale : localeList) {
            DateFormat df;
            SimpleDateFormat DATE_SDF;
            if (currentLocale.toString().equals("ja")) {
                df = new SimpleDateFormat("MMMM", currentLocale);
                DATE_SDF = new SimpleDateFormat("dd MMMM yyyy", currentLocale);
            } else {
                df = new SimpleDateFormat("MMM", currentLocale);
                DATE_SDF = new SimpleDateFormat("dd MMM yyyy", currentLocale);
            }
            Calendar cal = Calendar.getInstance();
            for (int i = 0; i < 12; i++) {
                cal.set(Calendar.MONTH, i);
                String dateString = "11 " + df.format(cal.getTime()) + " 1970";
                Date parsedDate = null;
                try {
                    parsedDate = DATE_SDF.parse(dateString);
                } catch (ParseException e) {
                    e.printStackTrace();
                }
                System.out.println("parsedDate " + currentLocale + " (" + df.format(cal.getTime()) + "):" + parsedDate);
            }
        }
    }
}

这是结果:

一切顺利。现在我只需要调整我的 JQuery 日期格式和翻译以匹配。我必须将 for 循环中的迭代长度从 11 更新到 12 以包括十二月。 谢谢你!

Answer 1

这些不是有效日期 - 尝试使用此代码获取正确的短月份名称。例如，您会注意到四月是 Квіт，而不是 Кві。至于德国，三月应该是Mrz，而不是März。

public static void main(String[] args) throws IOException {
    Locale ukLocale = new Locale("uk");
    DateFormat df = new SimpleDateFormat("MMM", ukLocale);
    Calendar cal = Calendar.getInstance();
    for (int i = 0; i < 11; i++) {
        cal.set(Calendar.MONTH, i);
        System.out.println(df.format(cal.getTime()));
    }
}

哪些输出:

січ
лют
бер
квіт
трав
черв
лип
серп
вер
жовт
лист
