Incorrect save propertie file

Question

Hi!
I have the next propertie file Settings in folder Config:
[LOCALE]
Language=en
Country=US
I my code I have:
private static Properties properties;
private static final String FILE_NAME = "config" + File.separator + "Settings";
     private void initialization() {
          FileReader fileReader;
          try {
               properties = new Properties();
               fileReader = new FileReader(FILE_NAME);
               properties.load(fileReader);
               Locale.setDefault(new Locale(properties.getProperty("Language"), properties.getProperty("Country")));
               fileReader.close();
          } catch (FileNotFoundException e) {
               e.printStackTrace();
          } catch (IOException e) {
               e.printStackTrace();
     public static void setLocale(Locale locale) {
          FileWriter fileWriter;
          try {
               properties.setProperty("Language", locale.getLanguage());
               properties.setProperty("Country", locale.getCountry());
               fileWriter = new FileWriter(FILE_NAME);
               properties.store(fileWriter, "");
               fileWriter.close();
               Locale.setDefault(locale);
          } catch (IOException e) {
               e.printStackTrace();
When I change language I call method setLocale and the result is that in my propertie file I have:
#Wed Apr 09 19:18:22 EEST 2008
Language=ru
[LOCALE]=
Country=RU
Why?
I need the next content in file:
[LOCALE]
Language=ru
Country=RU

Answer 1

change location in my applicaton
e.g user work with English version and when want to chagne language to russian , in my application I change location (save in propertie file)
Internationalization.setLocale(new Locale("ru", "RU"));
public static void setLocale(Locale locale) {
          FileWriter fileWriter;
          try {
               properties.setProperty("Language", locale.getLanguage());
               properties.setProperty("Country", locale.getCountry());
               fileWriter = new FileWriter(FILE_NAME);
               properties.store(fileWriter, null);
               fileWriter.close();
               Locale.setDefault(locale);
          } catch (IOException e) {
               e.printStackTrace();
