What is a secure access level to a method for accessing another object

Question

I pass the object reference to the Util class. I try to call a protected method in the Util class, but I get a compile-time error -

The method setPositionChild(Field, int, int) from the type Manager is not visible

To call a protected method, is it required only in the implementation class? Can I pass the link to an external class and call the link there?

The protected method can be accessed from subclasses. Make this method public if you want to access from any class. More here

Also, as @Sean Patrick Floyd mentioned, from classes in one package!
