Given config: MessageBundle.properties: username = Username password = Password and MessageBundle_fr_FR.properties: username = Utilisateur password = le passe and MessageBundle_ru.properties…

Question

Options

• AUser = пользователь Pass = Пароль
• BThe compilation fails.
• CMissingResourceException is thrown at runtime.
• DUser = Utilisateur Pass = le passe
• EUser username

• A
  3% (1)
• B
  15% (6)
• C
  5% (2)
• D
  77% (30)

Explanation

Option D is partially correct in that Locale.FRANCE resolves to fr_FR, so ResourceBundle.getBundle("MessageBundle", Locale.FRANCE) finds and loads MessageBundle_fr_FR.properties, returning "Utilisateur" for username. However, the stated answer key appears to contain an error: new Locale("ru") resolves to MessageBundle_ru.properties, so msg_ru.getString("password") returns "Пароль" - not "le passe" as D claims. The actual output would be User = Utilisateur Pass = Пароль, which isn't cleanly represented by any single option as written (option E appears to be a corrupted/truncated distractor in this dump).

Why the other options are wrong:

• A is wrong on the username side - "пользователь" is the Russian username, but msg uses the French (fr_FR) bundle, not the Russian one.
• B is wrong - the code compiles fine; ResourceBundle, Locale, and getString are all valid Java SE API calls.
• C is wrong - both bundle files exist and both keys (username, password) are present in them, so no MissingResourceException is thrown.

Memory tip: Think of ResourceBundle.getBundle() as a "most specific match wins" lookup: it tries lang_COUNTRY → lang → default bundle in order, stopping at the first file found. Locale.FRANCE = fr_FR hits the _fr_FR file directly; new Locale("ru") (language-only) hits _ru directly - neither falls back to the default.
