不是“包私有”成员访问是否与默认（无修饰符）访问同义？ [英] Isn't "package private" member access synonymous with the default (no-modifier) access?

问题描述

我对某些文档使用的术语包私有以及默认访问的使用感到有些困惑。包私有和默认访问都不是受保护的同义词吗？

I am a little confused over the term "package private" that some of the documentation uses, along with the usage of "default access." Aren't package private and default access both synonymous with protected?

推荐答案

是的，它几乎是一样的。 protected修饰符指定只能在其自己的包中访问该成员（与package-private一样），并且另外，由另一个包中的类的子类访问。

Yes, it's almost the same. The protected modifier specifies that the member can only be accessed within its own package (as with package-private) and, in addition, by a subclass of its class in another package.
