javafx.application.Application class is an abstract class. And start() method is an abstract method of Application class.

In Java, we have to implement all the abstract methods of an abstract class when extending that abstract class. Here, we are implementing the abstract method (start() method) by overriding the start() method.

So, try this:

package application;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

    public class Main extends Application{

            public static void main(String[] args) {
                 launch(args);
            }

            @Override
            public void start(Stage primaryStage) throws Exception {

                Parent root = FXMLLoader.load(getClass().getResource("MyDocmnt.fxml"));
                Scene scene = new Scene(root);
                primaryStage.setTitle("My Tittle");
                primaryStage.setScene(scene);
                primaryStage.show();

            } 
    }

Try this:

package application;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Parent;
import javafx.scene.Scene;

    public class Main extends Application {

                @Override
                public void start(Stage primaryStage) {
                    try {
                        Parent root = FXMLLoader.load(getClass().getResource("/application/MyDocmnt.fxml"));
                        Scene scene = new Scene(root);
                        primaryStage.setTitle("My Title");
                        primaryStage.setScene(scene);
                        primaryStage.show();
                    } catch(Exception e) {
                        e.printStackTrace();
                    }
                }

        public static void main(String[] args) {
             launch(args);
        }

    }
