JavaFX, FXML Second scene is not opening - javafx

Question

I need help with this java code. I have three scene Login scene, Admin scene, and Player scene. When I run the program and enter that user and password the second should open. The problem now is that, the second scene is not opening. It's even connecting to the database, but that second scene is not opening. I have check the code, I can't see any problem with it. Can some please help me, what is happening.
Here is my main code.
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class GiantsLogin extends Application {
private static Stage stage;
#Override
public void start(Stage stage) throws IOException {
setPrimaryStage(stage);
Parent root = FXMLLoader.load(getClass().getResource("GiantsLogin.fxml"));
Scene scene = new Scene(root);
scene.getStylesheets().add(getClass().getResource("style.css").toExternalForm());
stage.setScene(scene);
stage.setTitle("Giants Login");
stage.show();
}
public static void setPrimaryStage(Stage primaryStage) {
stage = primaryStage;
}
public static Stage getPrimaryStage() {
return stage;
}
public static void main(String[] args) {
launch(args);
}
}
Here is the controller for my main:

}
}
public boolean connectCheck() {

dataName = dbName.getText();

switch (sType.getValue()) {
case "MySQL LOCAL":

break;

break;
case "SQL SERVER":

break;
default:

if (connect == null) {
connect = Connections.getconnect(num, dataName, serverName, password);
}
if (connect == null ) {
System.out.println("Still no connection");
}
if (stmt == null) {
try {
stmt = connect.createStatement();
connected = true;
} catch (SQLException e) {
Alert notify = new Alert(Alert.AlertType.INFORMATION);
notify.setTitle("Blank filed");
notify.setHeaderText(null);
notify.setContentText("Incorrect login.");
notify.showAndWait();
connected = false;
}
}
return connected;
}
private boolean isAllFieldFillup() {
boolean allInfo;
if (sType.getValue().equals("server type") && dbName.getText().isEmpty()

notify.setHeaderText(null);
notify.setContentText("You are missing some information.");
notify.showAndWait();
allInfo = false;
}
else {
allInfo = true;
}
return allInfo;
}
}
This is the where I set my stage for my Admin, and Player scene.
public void admindStage(Stage stage) throws IOException {
GiantsAdminController controller = new GiantsAdminController("Hello World!");
FXMLLoader loader = new FXMLLoader (getClass().getResource("GiantsAdmin.fxml"));
loader.setController(controller);
stage.hide();
stage.setScene(new Scene((Pane) loader.load()));
stage.show();
}
public void playerStage(Stage stage) throws IOException {
GiantsAdminController controller = new GiantsAdminController("Hello World!");
FXMLLoader loader = new FXMLLoader(getClass().getResource("GiantsPlayer.fxml"));
loader.setController(controller);
stage.hide();
stage.setScene(new Scene((Pane) loader.load()));
stage.show();
}
This is where I am call those two stage in the GiantsLoginController.
public void loginBClick (Event event) {
if (isAllFieldFillup()) {
switch(uType.getValue().trim()) {
case "Admin":
if (connectCheck()) {
try {
admindStage(GiantsLogin.getPrimaryStage());
}
catch (Exception e) {
}
}
case "Player":
if (connectCheck()) {
try {
playerStage(GiantsLogin.getPrimaryStage());
}
catch (Exception e) {
}
}
}
}
}
This is the controller for my Admin scene

Answer 1

the following is just a proposition!. with admindStage() method, do the following modification
public void admindStage(Stage stage) throws IOException {
GiantsAdminController controller = new GiantsAdminController("Hello World!");
FXMLLoader loader = new FXMLLoader (getClass().getResource("GiantsAdmin.fxml"));
loader.setController(controller);
//stage.hide();
stage.setScene(new Scene((Pane) loader.load()));
//stage.show();
}
Or using multiple stage:
public void admindStage() throws IOException {
GiantsAdminController controller = new GiantsAdminController("Hello World!");
FXMLLoader loader = new FXMLLoader (getClass().getResource("GiantsAdmin.fxml"));
loader.setController(controller);
Stage stage = new Stage();
stage.setScene(new Scene((Pane) loader.load()));
stage.show();
}
