public class test extends Application{ 

    Stage primaryStage; 

    @Override 
    public void start(final Stage stage) throws Exception { 

     primaryStage = stage; 

     Button showPopUp = new Button("Pop Up"); 
     final TextField name = new TextField(); 

     VBox vBox = new VBox(); 
     vBox.getChildren().add(name); 
     vBox.getChildren().add(showPopUp); 


     final Label hello = new Label(); 
     final TextField name2 = new TextField(); 
     Button ok = new Button("ok"); 
     Button cencel = new Button("cancel"); 

     VBox popUpVBox = new VBox(); 
     popUpVBox.getChildren().add(hello); 
     popUpVBox.getChildren().add(name2); 
     popUpVBox.getChildren().add(ok); 
     popUpVBox.getChildren().add(cencel); 

     final Popup popup = new Popup(); 
     popup.setAutoFix(false); 
     popup.setHideOnEscape(true); 
     popup.getContent().addAll(popUpVBox); 
     popup.setX(250); 
     popup.setY(175); 

     ok.setOnAction(new EventHandler<ActionEvent>() { 

      @Override 
      public void handle(ActionEvent t) { 
       name.setText(name2.getText()); 
      } 
     }); 

     cencel.setOnAction(new EventHandler<ActionEvent>() { 

      @Override 
      public void handle(ActionEvent t) { 
       popup.hide(); 
      } 
     }); 


     showPopUp.setOnAction(new EventHandler<ActionEvent>() { 

      @Override 
      public void handle(ActionEvent t) { 
       if (popup.isShowing()) { 
        popup.hide(); 
       } else { 
        hello.setText("hello.."+name.getText()); 
        popup.show(stage); 
       } 
      } 
     }); 

     Scene scene = new Scene(vBox); 

     primaryStage.setScene(scene); 
     primaryStage.setWidth(200); 
     primaryStage.setHeight(200); 
     primaryStage.show(); 
    } 

}
