推荐答案

如 API 中所述， SwingUtilities 是Swing实用程序方法的集合。在这种情况下，需要确保在Event Dispatch Thread中创建/修改Swing组件，或者 EDT 。另外，如 API ， invokeLater 。

As stated in the API, SwingUtilities is a collection of utility methods for Swing. In this case, it is needed to ensure that Swing components are created/modified in the Event Dispatch Thread, or EDT. Also, as stated in the API, invokeLater is used when an application thread needs to update the GUI.
