推荐答案

我建​​议你忘记它，因为它远离'好'的代码。坚持在一本体面的Java书中学到的东西，或者参见 http://download.oracle.com/javase/tutorial /index.html [ ^ ]官方教程。

I would suggest you forget it, as it is far from 'good' code. Stick to what you learn in a decent Java book, or see http://download.oracle.com/javase/tutorial/index.html[^] for the official tutorials.

这叫做封装，这是该语言的好处之一：

That is called encapsuation and is one of the benefits of the language:
