   // create a new ResourceBundle with specified locale
   ResourceBundle bundle =
   ResourceBundle.getBundle("hello", Locale.US);

   // print the text assigned to key "hello"
   System.out.println("" + bundle.getString("hello"));


Assuming we have a resource file available in your CLASSPATH, with the following content. This file will be used as an input for our example program:

hello=Hello World!

Let us compile and run the above program, this will produce the following result:

Hello World!
