Hi All,

In the JavaBeat'site, there's a question about entities and I'm not sure of the answer:

6)Which of the following statements are correct?

a)Entities supports inheritance
b)Abstract class and concrete classes can be entities.
c)Intance variables of an entity class can be public
d)Instance variables of an entity class must be private,protected or package visibility

The answer is a, b and d.

I agree with a and b.
But I can't find anywhere in the spec any restriction about the visibility of the fields.
So, for me, c is OK and d is false...

Any idea ?
