我正在编写一个用户的gui，我想创建一个方法，用以前定义的名称和操作创建不同数量的按钮。但是我不知道如何编写基于变量值的方法选择。谷歌没有提供任何有用的信息。有人能帮上忙吗？否则就不可能了？
下面是一些代码示例：

String[] actions={"testAction1","testAction2","testAction3"};
    defaultDialogWindow(actions,"test1", "test2", "test3");

    void defaultDialogWindow(String[] actions, String... bNames){
          double layoutX = 25;
          double spacing = 15;
          final Stage dialogStage = new Stage();
          dialogStage.initOwner(stage);
          dialogStage.initModality(Modality.WINDOW_MODAL);   
          dialogStage.setFullScreen(false);
          dialogStage.setResizable(false);
          dialogStage.setHeight(100);
          dialogStage.setWidth(bNames.length*100+(bNames.length-1)*spacing+2*layoutX+5);
          dialogStage.setScene(new Scene(buttonBuilder(actions,spacing,layoutX,bNames)));
          dialogStage.show();  
    }

    HBox buttonBuilder(String[] actions, double spacing,double layoutX,String... bNames){
          HBox lBar = new HBox(10);
          final ReadOnlyDoubleProperty menuWidthProperty = lBar.widthProperty();
          lBar.setAlignment(Pos.CENTER_LEFT);
          lBar.setLayoutX(layoutX);
          lBar.setSpacing(spacing);
          for(String text : bNames){
              Button newButton = new Button();
              newButton.setText(text);
              newButton.setFont(Font.font("Times New Roman", 22));
              newButton.prefWidthProperty().set(100);
              newButton.prefHeightProperty().set(50);
              newButton.setOnAction(new EventHandler<ActionEvent>() {
                  @Override
                  public void handle(ActionEvent paramT) {

                    **HERE MUST BE ACTION CALL BASED ON bNames VALUE**

                      System.out.println("button pressed");
                  }
              });
              lBar.getChildren().add(newButton);
          }
          System.out.println(lBar.prefWidth(-1));
          return lBar;
      }

      void testAction1(){
          System.out.println("this is test action one");
      }

      void testAction2(){
          System.out.println("this is test action two");
      }

      void testAction3(){
          System.out.println("this is test action three");
      }**strong text**
