How to get czech name of month

I have a problem with get a name of month in my language - Czech.

I want to get name of month as noun, but i always get inflected title. I tried many ways to get name, but all ways return inflected title of month name

For example I want to get name of october in czech "Říjen", but i get always "října".

    Calendar cal=Calendar.getInstance();
    SimpleDateFormat month_date = new SimpleDateFormat("MMMMMMMMM");
    String month_name = month_date.format(cal.getTime());
    DateFormat formatData = new SimpleDateFormat("d.MMMM yyyy H:mm");
    System.out.println(month_name);
    System.out.println(String.format(Locale.getDefault(),"%tB", cal));
    System.out.println(formatData.format(cal.getTime()));

All returns bad format for me. Is there any way to get right name of month? Thank you

In the end, I find the best solution for this problem. The problem is that "MMMM" format is used for "formatted name" of month (f.e. "ledna"). If you need a "standalone name" of month (f.e. "leden"), you need to use "LLLL" instead. Complete date format documentation can be found here:

https://docs.oracle.com/javase/8/docs/api/java/text/SimpleDateFormat.html

Here is simple example:

DateFormat.format("LLLL yyyy", date).toString().capitalize() // returns: Leden 2016

and 

DateFormat.format("MMMM yyyy", date).toString() // returns ledna 2016

This solution is working for all API's.

tl;dr

Month.OCTOBER.getDisplayName ( 
        TextStyle.FULL_STANDALONE , 
        new Locale ( "cs", "CZ" ) 
)

říjen

Thanks to the Answer by MikeX for showing this is a “standalone” language issue. Unlike English, some languages such as Czech alter the spelling of the month depending on the context of its usage.

Using java.time

The modern approach uses the java.time classes. The Question and other Answers are outdated, using the troublesome old date-time classes (Calendar, SimpleDateFormat, DateFormat, etc.) that are now legacy, supplanted entirely by the java.time classes. See below for back-port to Android.

The Month enum provides a method for localizing the name of the month: Month::getDisplayName. Pass a TextStyle indicating full-narrow-short and whether you want the standalone or combo type.

When can loop through these to see all the possible results.

Locale locale = new Locale ( "cs", "CZ" );
for ( Month month : EnumSet.allOf ( Month.class ) ) {
    System.out.println ( "\nMonth: " + month );
    for ( TextStyle textStyle : EnumSet.allOf ( TextStyle.class ) ) {
        String output = month.getDisplayName ( textStyle, locale ) + "  | " + textStyle;
        System.out.println ( output );
    }
}

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

You may solved this already, but here is the solution. I made a little research and the reason is the change in java.text.DateFormatSymbols in Java 8 (see compatibility guide).

There is a difference between formatting and standalone forms. Formatting forms: ledna, února, března, etc.; Standalone forms: leden, únor, březen, etc.

Also according to rules of the language the name of month when it stands alone starts with lower character, unless it begins the sentence.

This code will provide you the desired result.

public static void main(String[] args) {
  Calendar cal = Calendar.getInstance();
  Locale loc = new Locale("cs", "CZ"); 
  System.out.println(cal.getDisplayName(Calendar.MONTH, Calendar.LONG_STANDALONE, loc));
}

Using this sample code 

public static void main(String[] args) {
    Calendar cal= Calendar.getInstance();
    Locale loc = new Locale("cs", "CZ"); 
    System.out.println(String.format(loc,"%tB", cal));
}

I receive output

?íjen

Which looks like what you want (I explicitly defined your Locale).
