Internationalization also known as I18N is used for displaying content specific to the locale based on their languages, currencies and formatting conventions.Resource bundle is the file that contains the key/value pairs for the default language of your application. The naming format for this file is

bundlename_language_country_variant.properties

For example, if you have a bundle named ApplicationResource for the English language in the Unites States for the Windows platform, then your properties file name would be 

ApplicationResource_en_US_WIN.properties.

Lets take a senario in which the user can see the same page in four different languages like English, French, German and Italian. The jsp page gets displayed according to the language selected by the user.Our default resource bundle is ApplicationResource.properties file.
