为什么class不能是protected？

Question

protected是将成员访问限制在派生类中。你若是可以protected一个class，那就没意义了。因为类不是成员。

Answer 2

inner class 可以是 friendly, protected, private
但是最外层的 class 只能是 public 和 friendly
这是死规定

Answer 3

呵呵，Protected主要用在继承的子类上可见（在很多语言里面，不过Java有点区别）。如果class 使用Protected，那这对什么可见呀？

Answer 4

外层的 class 只能是 public 和 friendly，不要抠死理了！！

Answer 6

嗯，有道理，有些东东就是死规定！！要抠真正原因就得看看JAVA的编译原理和执行机制了
