+/**
+ * <code>PropertyResourceBundle</code> is a concrete subclass of
+ * <code>ResourceBundle</code> that manages resources for a locale
+ * using a set of static strings from a property file. See
+ * {@link ResourceBundle ResourceBundle} for more information about resource
+ * bundles.
+ *
+ * <p>
+ * Unlike other types of resource bundle, you don't subclass
+ * <code>PropertyResourceBundle</code>. Instead, you supply properties
+ * files containing the resource data. <code>ResourceBundle.getBundle</code>
+ * will automatically look for the appropriate properties file and create a
+ * <code>PropertyResourceBundle</code> that refers to it. See
+ * {@link ResourceBundle#getBundle(java.lang.String, java.util.Locale, java.lang.ClassLoader) ResourceBundle.getBundle}
+ * for a complete description of the search and instantiation strategy.
+ *
+ * <p>
+ * The following <a name="sample">example</a> 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 <code>PropertyResourceBundle</code>, and the text
+ * therefore is the content of the file "MyResources_de.properties"
+ * (a related <a href="ListResourceBundle.html#sample">example</a> shows
+ * how you can add bundles to this family that are implemented as subclasses
+ * of <code>ListResourceBundle</code>).
+ * 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.
+ * <blockquote>
+ * <pre>
+ * # MessageFormat pattern
+ * s1=Die Platte \"{1}\" enthält {0}.
+ *
+ * # location of {0} in pattern
+ * s2=1
+ *
+ * # sample disk name
+ * s3=Meine Platte
+ *
+ * # first ChoiceFormat choice
+ * s4=keine Dateien
+ *
+ * # second ChoiceFormat choice
+ * s5=eine Datei
+ *
+ * # third ChoiceFormat choice
+ * s6={0,number} Dateien
+ *
+ * # sample date
+ * s7=3. März 1996
+ * </pre>
+ * </blockquote>
+ *
+ * <p>
+ * <strong>Note:</strong> PropertyResourceBundle can be constructed either
+ * from an InputStream or a Reader, which represents a property file.
+ * Constructing a PropertyResourceBundle instance from an InputStream requires
+ * that the input stream be encoded in ISO-8859-1. In that case, characters
+ * that cannot be represented in ISO-8859-1 encoding must be represented by
+ * <a href="http://java.sun.com/docs/books/jls/third_edition/html/lexical.html#3.3">Unicode Escapes</a>,
+ * whereas the other constructor which takes a Reader does not have that limitation.
