- public class PropertyResourceBundle
- extends ResourceBundle
PropertyResourceBundle is a concrete subclass of
ResourceBundle that manages resources for a locale
using a set of static strings from a property file. See
ResourceBundle for more information about resource
bundles. See Properties for more information
about properties files, in particular the
information on character encodings.
Unlike other types of resource bundle, you don't subclass
PropertyResourceBundle . Instead, you supply properties
files containing the resource data. ResourceBundle.getBundle
will automatically look for the appropriate properties file and create a
PropertyResourceBundle that refers to it. See
ResourceBundle.getBundle
for a complete description of the search and instantiation strategy.
The following example shows a member of a resource
bundle family with the base name "MyResources".
The text defines the bundle "MyResources_de",
the German member of the bundle family.
This member is based on PropertyResourceBundle , and the text
therefore is the content of the file "MyResources_de.properties"
(a related example shows
how you can add bundles to this family that are implemented as subclasses
of ListResourceBundle ).
The keys in this example are of the form "s1" etc. The actual
keys are entirely up to your choice, so long as they are the same as
the keys you use in your program to retrieve the objects from the bundle.
Keys are case-sensitive.
