How to refresh database tableview after updating or Deleting In Javafx?

I have two Controller class(Controller and Dailog Controller). COntroller class has tableView. On Double click on Tableview row the Dialog popup. The dialogController class has two button i.e update and delete.
The Update button updating and deleting data in database. After updating or deleting i want to refresh tableview. The problem is tablview refresh method is in Controller class. So how can i refresh it?

int count = mysqlConnection.insertTask(getTask);
if(count > 0)
{
Alert alert = new Alert(AlertType.INFORMATION);
alert.setTitle("Saved");
alert.setContentText("Task Saved");
alert.show();
textArea.clear();
}
}

alert.setTitle("Empty TextArea");
alert.setContentText("Please write the task");

Snapcshot of Application

You can add this to the DialogBoxController class:
public class DialogBoxController {
private Controller controller;
public void setController(Controller controller){
this.controller = controller;
}
#FXML
public void delete(ActionEvent event){
// Your code
controller.refreshTable();
closeStage(event);
}}
And in the Controller:
DialogBoxController dialog = loader.getController();
dialog.editTask(selectedTask);
dialog.setController(this);

uploading image to localhost mysql

I want to save image file to my localhost MySQL database. Created Image (blob) column in personalDetails table.
As in screenshot, when I click on 'save' button every values correctly goes in database, but I can't do it for image .I've tried a lot of ways, but can't make it work. Here is all page code. There is also other connection code between data and MySQL. How can I make it ?

Passing Parameters from a controller to another gives java.lang.NullPointerException

I'm trying to get the username that somebody uses to Login, then insert it into a db when somebody makes an apointment
This is the "Programaritest" table
ID_programare | Nume | Prenume | Data | Ora | Departament | Doctor | Username | Nr_telefon
This is the accounts table where the username is saved as Unique
ID_account | Username | Password | Email | Nume | Prenume | Admin
The input of the username is gotten from fxml via a textfield, in GetUsername method, I've pointed it out below

The error message that I am getting when trying to add a new appointment is:
Caused by: java.lang.NullPointerException
at LicentaApp.AddProgramareController.AddProgramare(AddProgramareController.java:103)
At line 103: String numeutilizator=Numeutilizator.getText();
So the data from numeutilizator is not what the input is putting out, that means i failed passing the parameter from a controller to another.
P.S I have followed this Passing Parameters JavaFX FXML, couldn't figure it out.

There are multiple reasons this exception could happen:
The controller instance is not used with a fxml
the fxml the controller instance is used with does not contain a element with fx:id="Numeutilizator"
Therefore I'll post a simple example that gets a single string from a scene designed using fxml:
Application class
#Override
public void start(Stage primaryStage) {
Button btn = new Button("Get input");
btn.setOnAction((ActionEvent event) -> {
FXMLLoader loader = new FXMLLoader(getClass().getResource("dialog.fxml"));
Parent p;
try {
p = loader.load();
} catch (IOException ex) {
throw new RuntimeException(ex);
}
DialogController controller = loader.getController();
Stage stage = new Stage(StageStyle.UTILITY);
stage.initOwner(primaryStage);
stage.setScene(new Scene(p, 100, 100));
stage.showAndWait(); // display window and wait for close
if (controller.isCanceled()) {
System.out.println("canceled");
} else {
System.out.println("input submitted: " + controller.getText());
}
});
StackPane root = new StackPane(btn);
Scene scene = new Scene(root, 300, 300);
primaryStage.setScene(scene);
primaryStage.show();
}
dialog.fxml
<VBox xmlns:fx="http://javafx.com/fxml/1" fx:controller="fxml.DialogController">
<children>
<TextField fx:id="input"/>
<Button text="submit" onAction="#submit"/>
<Button text="cancel" onAction="#cancel"/>
</children>
</VBox>
fxml.DialogController
public class DialogController {
#FXML
private TextField input;
private boolean canceled = true;
public boolean isCanceled() {
return canceled;
}
public final String getText() {
return input.getText();
}
private void close(boolean canceled) {
this.canceled = canceled;
input.getScene().getWindow().hide();
}
#FXML
private void submit() {
close(false);
}
#FXML
private void cancel() {
close(true);
}
}
Instead of retrieving the info you could also pass a object containing logic to handle certain events to the controller before showing the fxml's content.

JavaFX - How to add Item to ListView from different Stage?

How can i add an item to an already existing ListView from a different Stage (Window).
Basically i just want to add Text to the ListView from Window 2 to the ListView in Window 1.
Thanks in advance.
Sorry i forgot this is what i've got so far in my controller class: (im a beginner in javafx ..)
(below i try to add a String to the ListView but this doesnt work...and i dont know why )
public class ClientGUIController implements Initializable {
#FXML private Text usernameText;
#FXML private Button cancelButtonNewDate;
#FXML private TextField newDateTitel,newDateJahr;
#FXML private TextArea newDateNotiz;
#FXML private ComboBox<String> newDateTag,newDateMonat,newDateStunde,newDateMinute;
#FXML private ListView<String> terminListView;
private ObservableList<String> termine =
FXCollections.observableArrayList();
private ObservableList<String> listItems = FXCollections.observableArrayList("Add Items here");
#Override
public void initialize(URL location, ResourceBundle resources) {
}
public Text getUsernameText() {
return usernameText;
}
public void setUsernameText(String username ) {
this.usernameText.setText(username);
terminListView.setItems(listItems);
listItems.add("test");
}
public void newDate() {
Stage newDate = new Stage();
Parent root;
try {
root = FXMLLoader.load(getClass().getResource("newDate.fxml"));
// FXMLLoader loader = new FXMLLoader();
// root = (Parent) loader.load(getClass().getResource("NewDate.fxml").openStream());
} catch (IOException e) {
e.printStackTrace();
return;
}
Scene sceneNewDate = new Scene(root);
// sceneNewDate.getStylesheets().add(getClass().getResource("Style.css").toExternalForm());
newDate.setTitle("Neuer Termin");
newDate.setScene(sceneNewDate);
newDate.show();
}
public void createNewDate() throws IOException {
// Termine meinTermin = new Termine(Integer.parseInt(newDateTag.getValue()), Integer.parseInt(newDateMonat.getValue()), Integer.parseInt(newDateJahr.getText()), newDateTitel.getText(), newDateNotiz.getText(),
// Integer.parseInt(newDateStunde.getValue()), Integer.parseInt(newDateMinute.getValue()));
//Add item to ListView
listItems.add("test"); <- this doesnt work
}
public void closeDialogue(){
Stage stage = (Stage) cancelButtonNewDate.getScene().getWindow();
stage.close();
}
}

One way to do this is to pass listItems to the controller for newDate.fxml, so it can just add to that list. So, assuming the controller class for newDate.fxml is NewDateController, you would do something like:
public class NewDateController {
private ObservableList<String> data ;
public void setData(ObservableList<String> data) {
this.data = data ;
}
// other code as before...
// button handler:
#FXML
private void handleButtonPress() {
data.addItem("test");
}
}
Then in your ClientGUIController, load the fxml like this:
public void newDate() {
Stage newDate = new Stage();
Parent root;
try {
FXMLLoader loader = new FXMLLoader(getClass().getResource("newDate.fxml"));
root = loader.load();
NewDateController controller = loader.getController();
controller.setData(listItems);
} catch (IOException e) {
e.printStackTrace();
return;
}
Scene sceneNewDate = new Scene(root);
newDate.setTitle("Neuer Termin");
newDate.setScene(sceneNewDate);
newDate.show();
}
