在不使用Platform.RunLater的情况下使用任务更新javafx

import javafx.application.Application;
import javafx.concurrent.Task;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class UpdateJavaFXWithoutPlatformRunLater extends Application {

    @Override
    public void start(Stage primaryStage) {
        Label label = new Label("Initial Value");

        Button button = new Button("Update Value");
        button.setOnAction(event -> {
            Task<String> task = new Task<String>() {
                @Override
                protected String call() throws Exception {
                    // 模拟耗时操作
                    Thread.sleep(2000);
                    return "Updated Value";
                }
            };

            task.setOnSucceeded(e -> {
                String updatedValue = task.getValue();
                label.setText(updatedValue);
            });

            new Thread(task).start();
        });

        VBox root = new VBox(label, button);
        Scene scene = new Scene(root, 200, 100);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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