如何在javafx中绘制一条直线，当用户移动鼠标时它会自动更新？

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.AnchorPane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Line;
import javafx.stage.Stage;

public class DrawLineExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        // 创建根节点
        AnchorPane root = new AnchorPane();
        root.setPrefSize(400, 400);
        root.setStyle("-fx-background-color: white");

        // 创建直线
        Line line = new Line();
        line.setStroke(Color.BLACK);
        line.setStrokeWidth(2);

        // 监听鼠标移动事件
        root.setOnMouseMoved((MouseEvent event) -> {
            // 更新直线的结束点坐标
            line.setEndX(event.getX());
            line.setEndY(event.getY());
        });

        // 将直线添加到根节点
        root.getChildren().add(line);

        // 创建场景
        Scene scene = new Scene(root);

        // 设置舞台
        primaryStage.setTitle("Draw Line Example");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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