I got data in tableView with the following code.

Now How to make changes in database with this tableView.

Can any body help me?

//tableView codes
try{
data = FXCollections.observableArrayList();
String SQL = "SELECT * from accounts";
//ResultSet
ResultSet rs = db.con.createStatement().executeQuery(SQL);

/**********************************
* TABLE COLUMN ADDED DYNAMICALLY *
**********************************/
for(int i=0 ; i<rs.getMetaData().getColumnCount(); i++){
//We are using non property style for making dynamic table
final int j = i;
acctCode.setCellValueFactory(new Callback<CellDataFeatures<ObservableList,String>,ObservableValue<String>>(){
public ObservableValue<String> call(CellDataFeatures<ObservableList, String> param) {
return new SimpleStringProperty(param.getValue().get(0).toString());
}
});
acctName.setCellValueFactory(new Callback<CellDataFeatures<ObservableList,String>,ObservableValue<String>>(){
public ObservableValue<String> call(CellDataFeatures<ObservableList, String> param) {
return new SimpleStringProperty(param.getValue().get(1).toString());
}
});
acctTypeId.setCellValueFactory(new Callback<CellDataFeatures<ObservableList,String>,ObservableValue<String>>(){
public ObservableValue<String> call(CellDataFeatures<ObservableList, String> param) {
return new SimpleStringProperty(param.getValue().get(2).toString());
}
});
tableView.getColumns();
}

/********************************
* Data added to ObservableList *
********************************/
while(rs.next()){
//Iterate Row
ObservableList<String> row = FXCollections.observableArrayList();
for(int i=1 ; i<=rs.getMetaData().getColumnCount(); i++){
//Iterate Column
row.add(rs.getString(i));
}
data.add(row);
}
//FINALLY ADDED TO TableView
tableView.setItems(data);
tableView.getItems();
}catch(Exception e){
e.printStackTrace();
System.out.println("Error on Building Data");
}
}
