javaFX - tableview getting selected items - database

Question

How can I get a selected item in a row from tableview in javaFX with Sqlite Database.
I am now using this to get the Index of the row:
(...)
#FXML
private ObservableList<UserData> data;
#FXML
private TableView table;
#FXML
private void pressTableAction() {
System.out.println("Selected index: " +table.getSelectionModel().getSelectedIndex());
}
(...)
public void initialize (URL url, ResourceBundle rb) {
try {
con = DataBaseConnection.getConnected();
stat = con.createStatement();
data = FXCollections.observableArrayList();
ResultSet rs = con.createStatement().executeQuery("SELECT * FROM person");
while (rs.next()) {
data.add(new UserData(rs.getInt("p_id"), rs.getString("Name")));
}
column1.setCellValueFactory(new PropertyValueFactory("p_id"));
column2.setCellValueFactory(new PropertyValueFactory("Name"));
table.setItems(null);
table.setItems(data);
} catch (Exception e) {
e.printStackTrace();
System.out.println("Error on Building Data");
}
Public static class UserData {
private IntegerProperty p_id;
private StringProperty Name;
private UserData(Integer p_id, String Name) {
this.p_id = new SimpleIntegerProperty (p_id);
this.Name = new SimpleStringProperty(Name);
}
public IntegerProperty p_idProperty() {
return p_id;
}
public StringProperty NameProperty() {
return Name;
}
}
My db looks like this:
CREATE TABLE person (p_id INTEGER PRIMARY KEY AUTOINCREMENT, Name VARCHAR(30) NOT NULL);
How can I get the p_id or the Name of the row I clicked?
#FXML
private void pressTableAction() {
System.out.println("Selected index: " + table.getSelectionModel().getSelectedIndex());
System.out.println("Selected p_id: " + ????)
}

First, do not use raw types for your table and table columns. Your IDE should be generating lots of warnings for this. So you should do
#FXML
TableView<UserData> table ;
instead of the declaration you have. Similarly the columns should be declared with the appropriate types.
If your model class UserData follows the standard JavaFX properties pattern, it will have a getP_id() method, and you can do
UserData selected = table.getSelectionModel().getSelectedItem();
System.out.println("Selected p_id: "+selected.getP_id());
