Question

I need to parse a date into 11 different languages. So far, only two are giving me trouble: German and Ukrainian.

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();
            }
        }
    }
}

The output for this test is:

parsedGermanDate:Sun Jan 11 00:00:00 MST 1970
parsedGermanDate:Wed Feb 11 00:00:00 MST 1970

Why is it that some of these work and others do not? What can I do to get them all to work? I am using Java version "1.7.0_11".

I adjusted the code that assylias provided to fit into my original example:

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);
            }
        }
    }
}

This is the result:

Everything worked out. Now I just need to adjust my JQuery date format and translations to match. I had to update the iteration length in the for loop from 11 to 12 to include December. Thank you assylias!!

Solution

These are not valid dates - try this code to get the proper short month names. So you'll notice that April is Квіт, not Кві, for example. As for Germany, March should be Mrz, not 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()));
    }
}

which outputs:

січ
лют
бер
квіт
трав
черв
лип
серп
вер
жовт
лист
