The example below shows how to use java.util.ResourceBundle.getBundle() method to get the resource bundle Greetings_en_US.properties in a Java program.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a resource bundle in default locale
    ResourceBundle bundle = ResourceBundle.getBundle("Greetings");

    //printing the text assigned to "greet" 
    //key in the bundle
    System.out.println(bundle.getBundle("greet"));   
  }
}

The output of the above code will be:

Hello World!
