Locale-Sensitive Java Methods

The Java programming language was designed from the ground up to be cross-platform and to support fully internationalized application development. It fully supports Unicode and defines all String types as UTF-16. Further, Java has a number of native classes that facilitate international application development. Java has extremely robust locale-sensitive support, incorporating such functionality into standard classes and methods. Please see the Java Internationalization Trail for more information about Java's I18n capabilities .

Potentially Locale-Sensitive I18n Methods

The following list of functions are considered potentially locale-sensitive in the context of internationalized software development. In most cases, the method is potentially locale-sensitive because a signature exists that does not include the Java Locale object. These methods will use a default locale when unspecified. For true internationalization, these methods should be updated to be locale-specific to the user.
