code:

import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.web.*;
import javafx.scene.image.*;  

public class Main1 extends Application {
   
  
    public void start(Stage stage)
    {
        try {
   
          
            stage.setTitle("Fierce Pcs");
   
          
            WebView w = new WebView();
   
           
            WebEngine e = w.getEngine();
   
          
            e.load("https://www.example.com/");
            stage.getIcons().add(new Image(getClass().getResourceAsStream("icon.png")));
           
            Scene scene = new Scene(w, w.getPrefWidth(), 
                                     w.getPrefHeight());
   
          
            stage.setScene(scene);
   
            stage.show();
        }
   
        catch (Exception e) {
   
            System.out.println(e.getMessage());
        }
    }
   
  
    public static void main(String args[])
    {
   
       
        launch(args);
    }
}

the command which i give the command prompt:

java --module-path %PATH_TO_FX% --add-modules javafx.fxml,javafx.web C:\Users\example\OneDrive\Desktop\Main1.java

CodePudding user response：

Try this:

    launch(Main1.class, args);

Or stay with launch(args) and compile your Main1.java to Main1.class and run (i suppose this is the default (none) package):

     javac --module-path %PATH_TO_FX% --add-modules javafx.fxml,javafx.web Main1.java
     java --module-path %PATH_TO_FX% --add-modules javafx.fxml,javafx.web Main1
