//printing the text assigned to "greet"
//key in the bundle
System.out.println(bundle.getString("greet"));
//clearing cache used by base system classloader
System.out.println("Clearing Cache. Please wait...");
bundle.clearCache(ClassLoader.getSystemClassLoader());
System.out.println("Cache Cleared.");
}
}
The output of the above code will be:
