您的Java教科书说了什么？

如果没有相关部分，请将其丢弃。<

这里是一些很好的教程的链接。下载Sun的教程。它得到了所有这一部分。

And what does your Java textbook say?
If it doesn''t have a section for that, please throw it away.

Here are some links to some good tutorials. Download Sun''s tutorial. Its got a section for all that.

内部类的重要性在于，它们使生活更轻松，更安全。对于所有内容，您可以在单独的文件中使用单独的类，但通常您只想在另一个类中使用某个类，并且在使用它时就是这样。它甚至可以是私有类，因为只有该文件中的其他类才能看到它。 （这使它不那么脆弱。）

The importance of inner classes is, that they make life easier and safer. You could have separate classes in separate files for everything, but often you just want to use some class in one other class and that''s when you use it. It can even be a private class then, as only the other classes in that file will have to see it. (Which makes it less vulnerable.)

请记住，即使没有内部类，你通常也会在其他类中使用某些类。

Remember that you are usually using some class in some other class even without having inner classes.
