我试图将我的两个按钮直接放在我的标签下，并将所有内容都放在我的表格上 . 目前一切都只是印在一条线上 .

@Override public void start（Stage primaryStage）抛出Exception {

HBox hb = new HBox();
    hb.setSpacing(15);
    hb.setPadding(new Insets(15, 20, 5, 10));
    hb.setAlignment(Pos.CENTER);

    Label label = new Label("Greetings! Would you like to purchase cruise ticket for a family of two?");
    hb.getChildren().add(label);

    button1 = new Button("Yes");
    hb.getChildren().add(button1);
    button1.setOnAction(this);

    button2 = new Button("No");
    hb.getChildren().add(button2);
    button2.setOnAction(this);


    Scene scene = new Scene(hb, 550, 250);
    primaryStage.setTitle("Cruise for two!");
    primaryStage.setScene(scene);
    primaryStage.show();
}

    有关JavaFX中可用的许多布局选项的更多信息，Oracle提供了一个很好的教程，我建议您查看！

    HBox 将始终将其子项排列在水平行中 . 通过将 Label 添加到 HBox ，JavaFX正在做你正在告诉它的事情 .

    您还有 VBox ，它垂直排列节点 . 在 VBox 中，添加 Label ，然后添加 HBox ;他们将在 Label 下安排 HBox .

    import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.HBox;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class Main extends Application {

    private Button button1;
    private Button button2;

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

    @Override
    public void start(Stage primaryStage) {

        VBox root = new VBox(5);
        root.setPadding(new Insets(10));
        root.setAlignment(Pos.CENTER);

        HBox hb = new HBox();
        hb.setSpacing(15);
        hb.setPadding(new Insets(15, 20, 5, 10));
        hb.setAlignment(Pos.CENTER);

        Label label = new Label("Greetings! Would you like to purchase cruise ticket for a family of two?");
        root.getChildren().add(label);

        button1 = new Button("Yes");
        hb.getChildren().add(button1);

        button2 = new Button("No");
        hb.getChildren().add(button2);

        root.getChildren().add(hb);

        Scene scene = new Scene(root, 550, 250);
        primaryStage.setTitle("Cruise for two!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

    结果：
