Java OCA OCP Practice Question 2120

Question

Given the four properties files, what does this code print?. 

Cars_en.properties        Cars_fr.properties 
 engine=engine             engine=moteur 
 horses=123 

Cars_en_US.properties     Cars_fr_FR.properties 
 country=US                country=France 

Locale.setDefault(new Locale("fr", "CA")); 
ResourceBundle rb = ResourceBundle.getBundle( 
    "Cars", new Locale("en", "CA")); 

System.out.println(rb.getString("engine") + " " 
    + rb.getString("horses")); 

A.   engine 123
B.   moteur 123
C.   moteur null
D.   The code throws an exception at runtime.



A.

Note

The getBundle() method matches Cars_en.properties.

Since the requested locale of English Canada is not available, it uses the language-specific locale of English.

The engine key is in that properties file directly, so engine is retrieved as the value.

The horses key is also in that properties file, so 123 is used as the value, and Option A is the answer.
