推荐答案
JDialog和JFrame之间的区别在于，JDialog没有最大化/最小化按钮，并且您不能在其上设置DefaultCloseOperation.
The differences between JDialog and JFrame are, that JDialog has no maximize/minimize button, and you can not set a DefaultCloseOperation on it.
JDialog还会阻塞其他组件，直到将其关闭(等待用户交互).因此，如果您将其用作帮助"窗口，则用户将无法使其在后台打开并继续使用您的应用程序.
Also a JDialog blocks other components until it is closed (it waits for userinteraction). So if you use it as "Help" window, the user could not leave it open in background and continue working with your application.
如果用户只能阅读您的信息文本，而不能与您的帮助进行交互，则您应该使用 JFrame.
If the user can only read your info text, and can not interact with your help, you should use a JFrame.
如果用户可以选择JDialog，则应使用JDialog.按下Ok或Cancel键，他应该在选择某项之前不能执行任何操作.
A JDialog should be used if the user has the choice e.g. of pressing Ok or Cancel, and he should not be able to do anything before he has choosen something.
