Change date for other languages ?

[Edson Cezar]

I have a little doubt, when I execute this simple code, he return for me the String in English, in the case just the Month, but I wanted in portuguese.

Caso someone can help me, thanks a lot.

import java.text.*;
import java.util.*;

public class MonthFormat {

  public static void main(String args[]) throws ParseException {

  String s;
  String s1;
  String s2;
  String s3;
  
  Format formatter;
  Date date = new Date();
  
  formatter = new SimpleDateFormat("MMMM");  
  s = formatter.format(date);  // January 
  
  formatter = new SimpleDateFormat("dd");  
  s1 = formatter.format(date); 
  
  formatter = new SimpleDateFormat("yyyy");  
  s2 = formatter.format(date); 
  
  s3 = " de ";
  
  
  System.out.println("Month : " + s1+s3+s+s3+s2);
  
  }
}

I'm sure that SimpleDateFormat must have a setLocale method...

[Campbell Ritchie]

I don't think it has. The nearest I can find is that if you use System.getProperties you get user.country which corresponds to UK in my case. You can try changing that; of course if I change that to "FR" my computer will spend the next week trying to feed me snails and frogs and saying "pas manger le rosbif" (Don't eat roast beef)

So you will have to remember to change it back afterwards.

There are bound to be other similar properties elsewhere. Somebody else will doubtless know something sensible.

[Campbell Ritchie]

On another recent thread I noticed the getDateInstance method takes a Locale as a parameter, so that sounds more promising.

[Jesper de Jong]

Indeed SimpleDateFormat does not have a setLocale method, but it does have a constructor to which you can pass a Locale object:

DateFormat df = new SimpleDateFormat("d MMMM yyyy", new Locale("pt", "PT"));

System.out.println(df.format(new Date()));

You can also change the default locale, but not by changing a system property as Campbell suggests. Class Locale has a static setDefault method:

// Set the default locale to Portuguese / Portugal
Locale.setDefault(new Locale("pt", "PT"));

This will not be a persistent setting; it will remain in effect only for the JVM that is currently running your program.

First, thank for all, I did this example here:

import java.text.*;
import java.util.*;

public class MonthFormat {

  public static void main(String args[]) throws ParseException {

  String s;
//  String s1;
//  String s2;
//  String s3;
  
  Format formatter;
  Date date = new Date();
  DateFormat df = new SimpleDateFormat("MMMM"); 
  Locale BRAZIL = new Locale("pt","BR");
  
  df = DateFormat.getDateInstance(DateFormat.FULL, BRAZIL); 
  
//  formatter = new SimpleDateFormat("MMMM");  
    s = df.format(date);  // January 
//  
//  formatter = new SimpleDateFormat("dd");  
//  s1 = formatter.format(date); 
//  
//  formatter = new SimpleDateFormat("yyyy");  
//  s2 = formatter.format(date); 
//  
//  s3 = " de ";
  
  
  System.out.println("Month : " + s);
  
  }
}

Your output is this :

Sabado, 3 de Setembro de 2011

But I want this output :

3 de Setembro de 2011

I thank anyone who can help me

Thanks all for help me, I did this code, I know this code isn't the best way, but I tried

import java.text.*;
import java.util.*;

public class MonthFormat {

  public static void main(String args[]) throws ParseException {

  String s;
  
  Date date = new Date();
  DateFormat df = new SimpleDateFormat(""); 
  Locale BRAZIL = new Locale("pt","BR");
  
  df = DateFormat.getDateInstance(DateFormat.FULL, BRAZIL); 
  s = df.format(date);  // January 
  
  String[] s3 = s.split(","); 
    
  System.out.println("Month : " + s3[1]);
  
  }
}

The output of code is :

Month : 3 de Setembro de 2011 (I needed exactly this)

[Campbell Ritchie]

Can't you put something like "dd de MMMM de yyyy" into the df constructor? Or DateFormat.LONG instead of FULL?

Thank you,

I think this is the more simple that I can do :

Locale localeBR = new Locale("pt", "BR");  
  
SimpleDateFormat fmt = new SimpleDateFormat("dd 'de' MMMM 'de' yyyy", localeBR);  
            
System.out.println( fmt.format(new Date()) ); 

Thank for all
