## 30.18 java.util.PropertyResourceBundle (JDK 1.1)

###

This class is a concrete subclass of `ResourceBundle`. It reads a `Properties` file from a specified `InputStream` and implements the `ResourceBundle` API for looking up named resources from the resulting `Properties` object.

A `Properties` file contains lines of the form:

    name=value

Each such line defines a named property with the specified `String` value.

Although you can instantiate a `PropertyResourceBundle` yourself, it is more common to simply define a `Properties` file, and then allow `ResourceBundle.getBundle()` to look up that file and return the necessary `PropertyResourceBundle` object.

See also `Properties` and `ResourceBundle`.

    public class PropertyResourceBundle extends ResourceBundle {
        // Public Constructor
                public PropertyResourceBundle(InputStream stream) throws IOException;
        // Public Instance Methods
                public Enumeration getKeys();  // Defines ResourceBundle
                public Object handleGetObject(String key);  // Defines ResourceBundle
    }
