## Introduction ## When localizing your application, `ResourceBundle` can be a great way to load Strings from different locales. The only concrete implementation of ResourceBundle is `PropertyResourceBundle`, which allows us to load static Strings from a text file. Because `.properties` is a common file extension used for ResourceBundles, creating ResourceBundle objects using this file format would be the focus of this tutorial. Property files are commonly used to load application properties for Spring Boot projects, so if you have been working with Spring Boot, then this file format should be familiar to you; the only difference to what we create …
