Class PropertyResourceBundle

public class PropertyResourceBundle
extends ResourceBundle
This class is a concrete ResourceBundle that gets it resources from a property file. This implies that the resources are strings. For more information about resource bundles see the class ResourceBundle. You should not use this class directly, or subclass it, but you get an object of this class automatically when you call ResourceBundle.getBundle() and there is a properties file. If there is also a class for this resource and the same locale, the class will be chosen. The properties file should have the name of the resource bundle, appended with the locale (e.g. _de and the extension .properties. The file should have the same format as for Properties.load() An example of a properties file for the german language is given here. This extends the example given in ListResourceBundle. Create a file MyResource_de.properties with the following contents and put it in the CLASSPATH. (The char \u00e4 is the german umlaut) 
s1=3
s2=MeineDisk
s3=3. M\u00e4rz 96
s4=Die Diskette ''{1}'' enth\u00e4lt {0} in {2}.
s5=0
s6=keine Dateien
s7=1
s8=eine Datei
s9=2
s10={0,number} Dateien
s11=Die Formatierung warf eine Exception: {0}
s12=FEHLER
s13=Ergebnis
s14=Dialog
s15=Auswahlkriterium
