       AnchorPane anchor = new AnchorPane();
       AnchorPane.setTopAnchor(pagination, 10.0);
       AnchorPane.setRightAnchor(pagination, 10.0);
       AnchorPane.setBottomAnchor(pagination, 10.0);
       AnchorPane.setLeftAnchor(pagination, 10.0);
       anchor.getChildren().addAll(pagination);
       Scene scene = new Scene(anchor, 400, 250);
       stage.setScene(scene);
       stage.setTitle("PaginationSample");
       stage.show();
   }
}

上面的代码生成以下结果。
