This example show how to set icon of application window, by calling:

Stage.getIcons().add(applicationIcon);

Also show how to set icon dynamically at run-time, when 'Hello World' button clicked.

package javafx_applicationicon;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.image.Image;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
/**

public class JavaFX_ApplicationIcon extends Application {
 @Override
 public void start(final Stage primaryStage) {
 Button btn = new Button();
 btn.setText("Say 'Hello World'");
 btn.setOnAction(new EventHandler<ActionEvent>() {
 
 @Override
 public void handle(ActionEvent event) {
 System.out.println("Hello World!");
 
 //load another image from internet
 //and dynamically add it as new apllication icon
 Image anotherIcon = new Image("http://goo.gl/kYEQl");
 primaryStage.getIcons().add(anotherIcon);
 }
 });
 
 StackPane root = new StackPane();
 root.getChildren().add(btn);
 
 Scene scene = new Scene(root, 300, 250);
 
 //set icon of the application
 Image applicationIcon = new Image(getClass().getResourceAsStream("dukes_36x36.png"));
 primaryStage.getIcons().add(applicationIcon);
 
 primaryStage.setTitle("Hello World!");
 primaryStage.setScene(scene);
 primaryStage.show();
 }
 public static void main(String[] args) {
 launch(args);
 }
 
}
