 Commonly used strings in your Java program can be removed from the source code and placed in a separate file. This is called externalizing, and is useful for allowing changes to text displayed without impacting actual program logic. One example of where this is done is in internationalization, the practice of providing multilingual support in an application, allowing users to use an application in their native language.
