<h3>e892. Getting and Setting the Selected File of a JFileChooser Dialog</h3>
When setting the selected file, the file chooser dialog automatically sets
the current directory.
<pre> JFileChooser chooser = new JFileChooser();
// Set the current directory to the application's current directory
try {
// Create a File object containing the canonical path of the
// desired file
File f = new File(new File(<font color="#0066ff"><i>"filename.txt"</i></font>).getCanonicalPath());
// Set the selected file
chooser.setSelectedFile(f);
} catch (IOException e) {
}
// Show the dialog; wait until dialog is closed
chooser.showOpenDialog(<font color="#0066ff"><i>frame</i></font>);
// Get the currently selected file
File curFile = chooser.getSelectedFile();
</pre>
