Q:

Resource Bundle - anyone who care to explain? 

Yet again I am asking something for my project and I pretty much feel like I am a total newb in Java...
  Anyway, I was recently told about ResourceBundle.  My real problem is that I cannot understand the Oracle Documentation on the class in general and that I get some weird compile-time errors. 
  First off I made three Bundles mwb extends java.util. ResourceBundle, a second mwb_el extends mwb and a third mwb_en extends mwb.  I made a contents variable of type Object[][] and wrote a method getContents() that return cotents;!  Then I went into each class and changed the values for the second field in each line (not the key, the value).  No I am stuck at a point that I cannot really get how to handle getting the values. 
  I checked some tutorials and examples but I got even more confused.  What I need is someone to explain to me:

How do I make the mwb object I create and initialize in a class get the locale I want
it to. 
How do I get a certain value.  I tried getObject(), getString() even
the getContents() and even overriden the handleGetObject() to
    no avail. 
Thanks in advance! :) 

A:

Property file should have messages in key/value pairs. 
e.g

key1=message1
key2=message2

If you have a resource file called "MessagesBundle_en_US.properties" you can load it as follows. 
Locale locale = new Locale("en", "US");
ResourceBundle messages = ResourceBundle.getBundle("MessagesBundle", locale);

then messages.getString("key1") should return "message1".
