Which Java access modifier allows a member to be a

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.

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 :

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
