When setting the selected file, the file chooser dialog automatically sets the current directory. 
    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("filename.txt").getCanonicalPath());
    
        // Set the selected file
        chooser.setSelectedFile(f);
    } catch (IOException e) {
    }
    
    // Show the dialog; wait until dialog is closed
    chooser.showOpenDialog(frame);
    
    // Get the currently selected file
    File curFile = chooser.getSelectedFile();
