The differences between JDialog and JFrame are, that JDialog has no maximize/minimize button, and you can not set a DefaultCloseOperation on it. JDialog和JFrame之间的区别在于， JDialog没有最大化/最小化按钮，您无法在其上设置DefaultCloseOperation。

Also a JDialog blocks other components until it is closed (it waits for userinteraction). JDialog也会阻止其他组件，直到它关闭（它等待用户交互）。 So if you use it as "Help" window, the user could not leave it open in background and continue working with your application. 因此，如果您将其用作“帮助”窗口，则用户无法在后台打开它并继续使用您的应用程序。

If the user can only read your info text, and can not interact with your help, you should use a JFrame . 如果用户只能阅读您的信息文本，并且无法与您的帮助进行互动， 则应使用 JFrame 。

A JDialog should be used if the user has the choice eg of pressing Ok or Cancel , and he should not be able to do anything before he has choosen something. 如果用户可以选择例如按Ok或Cancel ，则应该使用JDialog ，并且在选择某些内容之前他不应该做任何事情。
