问题
I had to shorten the title a bit. Here's the full question:
In Java which access modifier allows a member to be accessed only by the subclasses in other package or any class within the package of that member's class?
I am thinking protected but my office mate says the answer is private.

回答2:
see this might help..you ! this is the scope of all access modifiers in java.
回答3:
Visibility of the properties of class for different access modifiers
——————————————————————————————————————
1) From the same class
Public , Protected, Private and Default
2) From any class in same package
Public, Protected and Default
3) From a subclass in same package
Public, Protected and Default
4) From subclass outside the same package
Public and Protected (by inheritance)
5) From any non-subclass or class outside the package
Public only
回答4:
It can't be private because private member methods are accessible only within the same class.
protected does not mean that a member will be accessed only by a subclass it specifically means that the classes are accessible within a package.
Your question is either wrong or you missed something on the way of asking your doubt.
Please have a look at the following :
