Question

i’m using some code to getfilenames and store it on a DB and everything works fine, but i wanted to show what files it stored on a TextArea, how can i do it?

Here is the code used to store the file names. BTW i’m doing this in NetBeans.

private void ActualizerBDActionPerformed(java.awt.event.ActionEvent evt) {                                             
        Conectar();
        File folder = null;
    try {
        String ppp = new File(".").getCanonicalPath();            
        folder = new File(ppp + "\\ImagensDB");
    } catch (IOException iOException) {
    }
        File[] listOfFiles = folder.listFiles();
        String query = "insert into dados (Num, Nome, Autor, Data, Preco, Categoria)" +"values(?,?,?,?,?,?)";
        PreparedStatement prepStmt=null;
    try {
        prepStmt = con.prepareStatement(query);
    } catch (SQLException ex) {
        Logger.getLogger(JanelaPrincipal.class.getName()).log(Level.SEVERE, null, ex);
    }
        for (int j = 0; j < listOfFiles.length; j++) {
                 if (listOfFiles[j].isFile()) {
            try {
                String text = listOfFiles[j].getName();
                String txsp[] = text.split("-");
                      prepStmt.setString(1, txsp[0]);
                      prepStmt.setString(2, txsp[1]);
                      prepStmt.setString(3, txsp[2]);
                      prepStmt.setString(4, txsp[3]);
                      prepStmt.setString(5, txsp[4]);
                      prepStmt.setString(6, txsp[5]);
                      prepStmt.execute(); // executa o INSERT
            } catch (SQLException ex) {
                Logger.getLogger(JanelaPrincipal.class.getName()).log(Level.SEVERE, null, ex);
            }
      }
}
        JOptionPane.showMessageDialog(null, "Dados Introduzidos com Sucesso!");
        try {
            con.close();
        } catch (SQLException ex) {
            Logger.getLogger(JanelaPrincipal.class.getName()).log(Level.SEVERE, null, ex);
        }

}

Thanks in advance.

Somewhere here you could

String text = listOfFiles[j].getName();
String txsp[] = text.split("-");
prepStmt.setString(1, txsp[0]);
prepStmt.setString(2, txsp[1]);
prepStmt.setString(3, txsp[2]);
prepStmt.setString(4, txsp[3]);
prepStmt.setString(5, txsp[4]);
prepStmt.setString(6, txsp[5]);
prepStmt.execute(); // executa o INSERT

myTextArea.append(text + "\n");

Of course you need to have build the ui first! Check out this for more elp
