<h3>e418. Importing Preferences</h3>
Preferences can be exported using <code>Preferences.exportNode()</code> (see
<a href="../java.util.prefs/Export.html" class="eglink"><b>e419</b> Exporting the Preferences in a Preference Node</a>) and <code>Preferences.exportSubtree()</code>
(see <a href="../java.util.prefs/ExportTree.html" class="eglink"><b>e420</b> Exporting the Preferences in a Subtree of Preference Nodes</a>). This exported data can
be imported using <code>Preferences.importPreferences()</code>.
<P> Each preference in exported data contains the path of the node
that held the preference. When the exported preference is later
imported, it is added to the node with the same path.
<P> This example demonstrates how to import a file of exported
preference data.
<pre>
// Create an input stream on a file
InputStream is = null;
try {
is = new BufferedInputStream(new FileInputStream(<font color="#0066ff"><i>"output.xml"</i></font>));
} catch (FileNotFoundException e) {
}
// Import preference data
try {
Preferences.importPreferences(is);
} catch (InvalidPreferencesFormatException e) {
} catch (IOException e) {
}
</pre>
