greet = Hello World!

In the below Java program, the java.util.ResourceBundle.clearCache() method is used to remove all resource bundles from the cache.

import java.util.*;

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

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

    //clearing cache 
    System.out.println("Clearing Cache. Please wait..."); 
    bundle.clearCache();
    System.out.println("Cache Cleared."); 
  }
}

The output of the above code will be:

Hello World!
Clearing Cache. Please wait...
Cache Cleared.
