Hi,
I disagree with the answer to this question:
19. Select all correct answers about what is the definition of an interface?
A) It is a blue print
B) A new data type
C) Nothing but a class definition
D) To provide multiple inheritance
Answer 19:
A) It is a blue print
B) A new data type
D) To provide multiple inheritance
I only chose D.
I didn't choose A because to me a blue print is the exact plan of something like a building blue print. With an interface, the implementation is blank. I would argue that a concrete class only is a blue print.
As for B, new compared to what? Are interfaces something new in the later releases of
Java?
