NetBeans supports expectation-driven development. I would find it more helpful if it could be eager.

Let's give an example. Let's suppose I have an interface C, but no class D. When I enter :
C c = new D();

NetBeans proposes to create the D class, and while doing so, the created D class does not implement C !

In that case, I would like that D created to implement the C interface.

IMHO they are other cases where such expectation-driven development could be eager, and then, more helpful.

PS : users may choose to have expectation-driven capabilities lazy or eager according to a NetBeans option.
