No. And you can easily check it up by writing code and trying to compile it. The indication that a class is abstract with the use of the keyword "abstract" is a sort of a fool-proof feature. It's pretty much the like the absence of non-declared variables.You can define an abstract class with...

From your code sample, it is apparent that you can use this list through the instance of A, because you made it an instance field of this class and it is public. In this respect, the problem solved.Both things are no good: 1) it's bad to make a field non-private; you should better use the...
