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. The resource bundle name that you pass to ResourceBundle.getBundle() is the file name of the properties file, not the class name of the object that is returned.

For example, if you say ResourceBundle.getBundle("MyResources", new Locale("fr", "FR")); the resource bundle lookup mechanism will search the class path for a file called MyResources_fr_FR.properties.

If a real class and a properties file with a particular name both exist, the class wins; the properties file will only be used if there is no class with the desired name.

In the following example, the keys are of the form "s1"... 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.

 s1=3
 s2=MeinDisk
 s3=3 Mar 96
 s4=Der disk '{1}' a {0} a {2}.
 s5=0
 s6=keine Datein
 s7=1
 s8=ein Datei
 s9=2
 s10={0}|3 Datein
 s11=Der Format worf ein Exception: {0}
 s12=ERROR
 s14=Resulte
 s13=Dialogue
 s15=Pattern
 s16=1,3
