Choose the correct answer:

What is the meaning of the relationship shown in the diagram below?

Aclass B is the creator of class A

Bclass A is dependent on class B

Cclass B is dependent on class A

Dclass A can be reached (torn class B

Suggested Answer: B

In UML 2, the dashed arrow with an open arrowhead represents a dependency relationship. In the context of class diagrams, a dependency relationship indicates that changes to one class (the independent class) may cause changes in the other class (the dependent class). The direction of the arrow specifies which class is dependent on which. In the given diagram, the arrow points from class A to class B, which means that class A is dependent on class B. This could manifest as class A using some services or functions of class B, for example.

I see it as C. B depends on A.

No, I feel like A needs B to function.

But what about A being the creator? That’s A, right?

Herminia 17 days ago

I agree, B makes sense.

Chauncey 22 days ago

I think it's B. Class A depends on class B.

Exactly! Dependency is key in this context.

B is the most logical choice here.

D? Really? That’s a stretch.

I lean towards B too. It shows a clear relationship.

No, Iluminada. That doesn't fit the diagram.

What if it's A? Class B creates A.

I agree with Valentine. The dependency makes sense.

Maxima 2 months ago

I feel confused about the diagram.

Valentine 2 months ago

I think it's B. Class A depends on class B.

I thought it was the other way around! This diagram is confusing.

Definitely B is the creator of A, that's how I see it.

Brandon 3 months ago

Wait, are we sure about that? Seems like A could stand alone.

I think class A is dependent on class B.

Peggie 4 months ago

I vaguely recall something about classes being able to reach each other, but I can't remember if that relates to D or not.

Jeffrey 5 months ago

I’m a bit confused about the terms used. Does "dependent" mean class A needs class B? If so, that might point to B, but I'm not certain.

Marci 5 months ago

I'm not entirely sure, but I feel like I've seen a similar question where the creator relationship was highlighted. Could it be A?

Wynell 5 months ago

I think I remember that a dependency means one class relies on another, so maybe it's B?
