This is my Main.java
package Library.Assistant.Ui.Main;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class MainLoader extends Application {
public static void main(String arg[]) {
launch(arg);
}
#Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("Main.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
}
