Why public constructor in abstract class?

[Former Member]

I am confused about a very basic thing.

Why must a constructor in an abstract class be public?

After all, it can only ever be called from the constructors

of the concrete subclasses, because of which I would

normally expect it to be protected.

Yes, it is confusing.

But till Release 7.0 EhP2, CONSTRUCTOR can only be declared as Public. From this release onwards, we can define the CONSTRUCTOR visibility also while defining the class. So, till this release all CONSTRUCTOR methods are public, no matter what type of class installation it is (i.e. Abstract or Private).
