Erro ao copiar pasta

Alguem pode me ajudar com o erro abaixo?

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
      try{
        FileInputStream oriChannel = new FileInputStream("C:\\Users\\jhonatan\\Documents\\aula9");
// Cria channel no destino
        
FileChannel destChannel = new FileOutputStream("C:\\").getChannel();
// Copia conteúdo da origem no destino
//destChannel.transferFrom(oriChannel, 0, oriChannel.size());

// Fecha channels
oriChannel.close();
destChannel.close();
JOptionPane.showMessageDialog(null,"ok");
      }catch (Exception e){
      e.printStackTrace();
      JOptionPane.showMessageDialog(null, e.getMessage());
      }
