How to make program runnable without moving Java library files to system

Question

I'm wondering why my programs in Swing can run at every machine which have Java installed, but JavaFX programs not. If I want to run my program in JavaFX i have to copy some JavaFX library files to JDK folder like here. The problem is: I don't want to force people to move some files into any folder! I want them to be able run the program just by clicking it and nothing else! I want to make it simple. Other Programs in Java don't force me to do that so how can i make my program like others? What should i do? Here are some example of code.

Main.java

package fxTutorial;

public class Main {
    public static void main(String[] args){
        Demo.main(args);
    }
}

Demo.java

package fxTutorial;

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.Event;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class Demo extends Application implements EventHandler {

    Button button = new Button();
    public static void main(String[] args){
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        primaryStage.setTitle("Application");
        button.setText("Button");
        button.setOnAction(this);

        StackPane stackPane = new StackPane();
        stackPane.getChildren().add(button);
        Scene scene = new Scene(stackPane,400,500);
        primaryStage.setScene(scene);
        primaryStage.show();

    }


    @Override
    public void handle(Event event) {
        if(event.getSource()==button)
            //Do something, like background changing - Whatever
    }
}

module-info.java

module Demo {
    requires javafx.fxml;
    requires javafx.controls;

    opens fxTutorial;
}
