爲什麼不按鈕添加到場景？

Question

package application; 

import java.awt.Button; 

import javafx.application.Application; 
import javafx.stage.Stage; 
import javafx.scene.Node; 
import javafx.scene.Scene; 
import javafx.scene.layout.BorderPane; 
import javafx.scene.layout.StackPane; 


public class Main extends Application { 

    Button button; //Declare Button 

    public static void main(String[] args) { 
     launch(args); //calls application 
    } 

    @Override 
    public void start(Stage primaryStage) throws Exception { 
     //comes from application pack 
     primaryStage.setTitle("Title Of Window"); //Main Stage 
     button = new Button(); //Creates Button 
     button.setLabel("Click Me"); 

     StackPane layout = new StackPane(); 
     layout.getChildren().add(button); //Button in Scene 
     Scene scene = new Scene (layout, 300, 250); //Sets Scene 
     primaryStage.setScene(scene); //Stage and Scene 
     primaryStage.show(); 



    } 

嘿傢伙，所以這是我第一次在JavaFX中創建一些東西，我想知道爲什麼我的按鈕在場景中不添加Layout.GetChildren()行，它不斷顯示下面添加的紅線。我正在使用Eclipse IDE。

你已經導入import java.awt.Button，你必須在javafx包中導入Button類。
