C is the correct answer, for example if you try to load
come-file_ES_ar.properties
Resources bundle then try to load these files i order
come-file_ES_ar.properties
come-file_ES.properties
come-file.properties (this is the default file)

Hi,

It will take the default properties file. Just run the following program with only default properties file (LabelsBundle.properties) and see the output.

So choice A is the correct answer.

One more request for EPractize Labs users.. please do not post any direct questions from EPractize Labs in forums.

import java.util.*;

public class PropertiesDemo {

static void displayValue(Locale currentLocale, String key) {

ResourceBundle labels =
ResourceBundle.getBundle("LabelsBundle",currentLocale);
String value = labels.getString(key);
System.out.println(
"Locale = " + currentLocale.toString() + ", " +
"key = " + key + ", " +
"value = " + value);

} // displayValue


static void iterateKeys(Locale currentLocale) {

ResourceBundle labels =
ResourceBundle.getBundle("LabelsBundle",currentLocale);

Enumeration bundleKeys = labels.getKeys();

while (bundleKeys.hasMoreElements()) {
String key = (String)bundleKeys.nextElement();
String value = labels.getString(key);
System.out.println("key = " + key + ", " +
"value = " + value);
}

} // iterateKeys


static public void main(String[] args) {

// Locale[] supportedLocales = {
// Locale.FRENCH,
// Locale.GERMAN,
// Locale.ENGLISH
// };




iterateKeys( Locale.FRENCH);

} // main

} // class



# This is the LabelsBundle.properties file // default
s1 = Computer_default
s2 = Platte_default
s3 = Monitor_default
s4 = Tastatur_default

Thanks & Regards

[elise robinson]

choice A is the correct answer.

look at the example from sun http://java.sun.com/docs/books/tutorial/i18n/resbundle/propfile.html

in that there are 3 properties files
LabelsBundle.properties (default)
LabelsBundle_de.properties
LabelsBundle_fr.properties

run the program for Locale.FRENCH and Locale.GERMAN by deleting the respective properties files except default.

thanks

I opt for C for the same reason which Santiago already mentioned.

[fitz face]

darya,can you demonstrate it by a java program? because i feel A is the right choice - fitz

Hi,

here is an example on how it works. We have theses files. Put them all in one directory if you want to test it.

HelloWorldResources.java

MyData.properties

MyData_fr.properties

MyData_fr_FR.properties

And here how they all look like:

HelloWorldResources.java

    
import java.util.*;
 
public class HelloWorldResources {
    public static void main(String [] argv) {
        ResourceBundle resources;
 
        try {
            resources = ResourceBundle.getBundle("MyData");
            System.out.println(resources.getString("Hi"));
        } catch (MissingResourceException mre) {
            System.err.println("MyData.properties not found");
        }
    }
}

MyData.properties (the default file)

Hi = Hello World!

MyData_fr.properties (the next file)

 
Hi = Salut tout le monde! (fr)   

MyData_fr_FR.properties

    
Hi = Salut tout le monde! (fr_FR)

Compile HelloWorldResources with javac HelloWorldResources.java and run it like:

java -Duser.language=fr -Duser.region=FR HelloWorldResources

Remember the output . Remove the MyData_fr_FR.properties from your directory and run the last line again.

What do you see now ?

I still stick to Answer C.

C is the correct Answer.

Refer to Java Internationalization Tutorial.

i, i think here the problem is the meaning of "will take the next properties file" ...
i assum that next propertie file is the next in the locale name hirarchy convention so ...
defaul is with no specification an as my example, y try to load a file named:

example.properties
for locale "es_AR"
so i got this files
example.properties -> this is default used for all other lenguajes (in english)
example_es.properties -> this is for alla spanish lenguajes
example_es_AR.properties -> this is for argentina

so when i try to load resource bundle, systen use locale, to fin the more "nearest" file to this specific locale.
So if try to load this bundle with argentina locale (es_AR) and i delete all file less than example.propertie, ResourceBundle do this:
1)first try to load especialized resource bundle for specific country in the locale (es= espa�ol-spanish AR==argentina) file is example_es_AR.properties
2) if not found, then try to load, resource for the locale lenguaje (es=spanish) so NEXT file is example_es.properties
3) if not found try to load default example.properties

so .. i think here the problem is the meanign a wath do you understand by "next file" ...

[Darya Akbari]

Is the example clear ?
