Populating textfields with tableview data when a line is clicked

问题

I want to use the data that I load in the tableview to populate some textfields. Is there a way to make a OnMouseClick action event that will populate a bunch of textfields with the data from the tableview?

I want this because I want to make an update method, in which you don't have to write the whole service details(like price, department, availability, and name) again just to change one particular thing, but this is not an issue, I know how to do it, just need to auto populate the textfields for it with the data provided by the tableview.

Provided some commentary in the code.

Code for the tableview:

public class ProgramariDBController implements Initializable {
@FXML
private TextField Serviciu1;
@FXML
private TextField Departament1;
@FXML
private TextField Pret1;
@FXML
private TextField Disponibilitate1;
@FXML
private Label rows;
@FXML
private Label rows;
@FXML
private TextField cpn;
@FXML
private TextField nume1;
@FXML
private TableView<DetaliiProgramari> ProgrDB;
@FXML
private TableColumn<DetaliiProgramari, String> Nume;
@FXML
private TableColumn<DetaliiProgramari, String> Prenume;
@FXML
private TableColumn<DetaliiProgramari, String> Data;
@FXML
private TableColumn<DetaliiProgramari, String> Ora;
@FXML
private TableColumn<DetaliiProgramari, String> Departament;
@FXML
private TableColumn<DetaliiProgramari, String> Doctor;
@FXML
private TableColumn<DetaliiProgramari, String> Nr_telefon;

public LogareController Numeutilzator = new LogareController();
private ObservableList<DetaliiProgramari> Info;

@Override
public void initialize(URL url, ResourceBundle ResurcesFORDAYS) {
    // TODO

}



@FXML
private void AfiseazaProgramari(ActionEvent event) {
    try {
      ConectaredB ConectaredB=new ConectaredB();
        Connection conectare=ConectaredB.logareDB();

        Info = FXCollections.observableArrayList();
        String CNP=cpn.getText();
        ResultSet IncDate = conectare.createStatement().executeQuery("SELECT *  FROM programari where CNP=" + CNP);
        while (IncDate.next()) {

            Info.add(new DetaliiProgramari(IncDate.getString(2), IncDate.getString(3), IncDate.getString(4),
                    IncDate.getString(5), IncDate.getString(6), IncDate.getString(7), IncDate.getString(8)));
            //I have something like this 
     Serviciu1.setText(IncDate.getString(2)); it did work, but it loaded the first thing that was created in TipServiciu, which is a column in the table, so that doesn't really help, and I won't even paste the whole thing, because it will just be confusing for no reason.
        }

    } catch (SQLException ex) {
        System.err.println("Error"+ex);
    }

    Nume.setCellValueFactory(new PropertyValueFactory<>("Nume"));
    Prenume.setCellValueFactory(new PropertyValueFactory<>("Prenume"));
    Data.setCellValueFactory(new PropertyValueFactory<>("Data"));
    Ora.setCellValueFactory(new PropertyValueFactory<>("Ora"));
    Departament.setCellValueFactory(new PropertyValueFactory<>("Departament"));
    Doctor.setCellValueFactory(new PropertyValueFactory<>("Doctor"));
    Nr_telefon.setCellValueFactory(new PropertyValueFactory<>("Nr_telefon"));

    ProgrDB.setItems(null);
    ProgrDB.setItems(Info);

}
@FXML 
private void delete(ActionEvent event) throws IOException  {
    try { 


        String sql = "delete FROM programari where CNP=? ";
        ConectaredB ConectaredB=new ConectaredB();
        Connection conexiune=ConectaredB.logareDB();
        PreparedStatement ps = conexiune.prepareStatement(sql);
        String CNP=cpn.getText();
        ps.setString(1, CNP);
        int count = ps.executeUpdate();

        rows.setText("rows" +count);

    } catch (Exception e) {
        // TODO: handle exception
    }
}
 }

The setters and getters, if they help in any way possible:

public class ServiciiSittersGettersController {

private final StringProperty Serviciu;
private final StringProperty Disponibilitate;
private final StringProperty Pret;
private final StringProperty Departament;



//Default constructor
public ServiciiSittersGettersController(String Serviciu, String Disponibilitate, String Pret, String Departament) {
    this.Serviciu = new SimpleStringProperty(Serviciu);
    this.Disponibilitate = new SimpleStringProperty(Disponibilitate);
    this.Pret = new SimpleStringProperty(Pret);
    this.Departament = new SimpleStringProperty(Departament);


}
public String getDepartament() {
    return Departament.get();
}

public StringProperty departamentProperty() {
    return Departament;
}

public void setDepartament(String departament) {
    this.Departament.set(departament);
}

public String getServiciu() {
    return Serviciu.get();
}

public StringProperty serviciuProperty() {
    return Serviciu;
}

public void setServiciu(String serviciu) {
    this.Serviciu.set(serviciu);
}

public String getDisponibilitate() {
    return Disponibilitate.get();
}

public StringProperty disponibilitateProperty() {
    return Disponibilitate;
}

public void setDisponibilitate(String disponibilitate) {
    this.Disponibilitate.set(disponibilitate);
}

public String getPret() {
    return Pret.get();
}

public StringProperty pretProperty() {
    return Pret;
}

public void setPret(String pret) {
    this.Pret.set(pret);
}

}

You have to add a listener to the TableView's getSelectionModel().selectedItemProperty().

Key code:

table.getSelectionModel().selectedItemProperty().addListener((obs, oldVal, newVal) -> 
{
    if (newVal != null) {
        tfFirstName.setText(newVal.getFirstName());
        tfLastName.setText(newVal.getLastName());
        tfEmail.setText(newVal.getEmail());
    }
});
