About Question enthuware.ocajp.i.v7.2.907 :

[crux terminatus]

Why does the constructor for the Bird class need to be made public? We are in a single package throughout this example. Providing default, not public, access to the constructor should be enough.

[admin]

Yes, protected and default will work as well. This has now been updated to make it clear.

thank you for your feedback!
