Generate and load html content dynamically using Java code

In this example, the html content in WebView is generated in run-time by Java code dynamically.

package javafx_webview;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.Region;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;

/**
*
* @web http://java-buddy.blogspot.com/
*/
public class JavaFX_Browser extends Application {

 private Scene scene;
 MyBrowser myBrowser;

 /**
  * @param args the command line arguments
  */
 public static void main(String[] args) {
     launch(args);
 }

 @Override
 public void start(Stage primaryStage) {
     primaryStage.setTitle("java-buddy.blogspot.com");
  
     myBrowser = new MyBrowser();
     scene = new Scene(myBrowser, 640, 480);
  
     primaryStage.setScene(scene);
     primaryStage.show();
 }

 class MyBrowser extends Region{
  
     WebView webView = new WebView();
     WebEngine webEngine = webView.getEngine();
          
     public MyBrowser(){
      
         webEngine.loadContent(genHtml());
      
         getChildren().add(webView);
     }
 }

 private String genHtml(){
  
     StringBuilder tHtml = new StringBuilder();
  
     tHtml.append("<DOCTYPE html>" + "\n");
     tHtml.append("<html lang='en-US'>" + "\n");
     tHtml.append("<head>" + "\n");
     tHtml.append("<meta charset=utf-8>" + "\n");
     tHtml.append("<title>Hello Java-Buddy!</title>" + "\n");
     tHtml.append("</head>" + "\n");
     tHtml.append("<body>" + "\n");
     tHtml.append("<p>Hello <a href='http://java-buddy.blogspot.com/'>Java-Buddy</a></p>" + "\n");
     tHtml.append("<img src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi46oUqWnNWLjbG8MZE3s1ljR5yGMN-vrGIJ077nAnO853BL4ufNSDj430W9acswVSbwX_b4EGi4K11aIm7OCSAhDoSr5uMQ4wYIQbppWUfxxAEDgQkJ9ni9f8Ig4Q-RP3JcaNHgjDG8s83/s150/duke_44x80.png'/>" + "\n");
     tHtml.append("</body>" + "\n");
     tHtml.append("</html>" + "\n");
  
     return tHtml.toString();     
 }
}
