Summary: This tutorial introduces you to the Java programming language's support for multilingual and multicountry environments. The tutorial begins with a general discussion of internationalization principles and concepts, and then moves on to an overview of the specific areas of Java internationalization support. The last few sections provide a more hands-on discussion of the areas basic to any internationalized Java application: Unicode and Java characters; locales and resource bundles; and formatting dates, numbers, and currencies.
