Discuss OMG OMG-OCUP2-FOUND100 Exam Topic 2 Question 24

Choose the correct answer:

Consider the following diagram fragment:

What makes this fragment invalid?

AA list of elements is not allowed in a package body.

Bclassone is missing a visibility.

CAn *interface is not allowed in a package

DPrivate elements are not allowed on the list.

EProtected elements are not allowed in a package.

FElement six is missing its stereotype.

Suggested Answer: F

In the given UML package diagram fragment, various elements are listed with stereotypes indicating their nature (class, interface). Stereotypes are used in UML to extend the vocabulary of UML in order to create new kinds of building blocks. They are typically enclosed in guillemets ( ).

The last element, 'six', does not have a stereotype indicating whether it's a class, interface, or some other kind of element. This lack of a stereotype leads to ambiguity about the nature of 'six'. Therefore, the fragment is considered invalid due to this omission.

All the other options do not constitute an error in the UML fragment: A) A list of elements is allowed in a package body. B) Visibility is not required for every element, especially within package diagrams. C) Interfaces are allowed in packages. D) Private elements are allowed in a package. E) Protected elements are also allowed in a package.

Therefore, the correct answer is:

F . Element six is missing its stereotype.

Not sure about that, I thought interfaces could be in packages.

Lawrence 11 months ago

I agree with Kate, visibility is key here!

Rashida 11 months ago

Wait, are protected elements really not allowed in a package?

Kate 11 months ago

I think classone missing visibility is a bigger issue.

Rikki 11 months ago

A list of elements is definitely not allowed in a package body.

Nancey 12 months ago

I definitely remember that stereotypes are important, so element six missing one might be a valid reason for invalidity.

Denny 12 months ago

I feel like I read that private elements can be included in lists, but maybe I misunderstood that part.

Mel 12 months ago

I practiced a similar question where interfaces were mentioned, but I can't recall if they can be in a package or not.

Ricki 1 year ago

I think I remember something about visibility in classes, but I'm not sure if it's specifically about "classone" here.

Leota 1 year ago

Ah, the missing stereotype on element six. That could be the issue. I'll make sure to look for any syntax or formatting problems in the diagram.

Annita 1 year ago

Private and protected elements - that's an interesting one. I'll double-check the visibility rules for package contents.

Brittney 1 year ago

I'm a bit confused by the interface in the package. Is that not allowed? I'll have to think through the package structure rules.

Kimi 1 year ago

Okay, let's see. A list of elements in a package body? That doesn't sound right. I'll go with option A.

Hayley 1 year ago

Hmm, this looks tricky. I'll need to carefully review the package body rules to figure out what's wrong here.

Odette 2 years ago

Wait, is this a trick question? I'm gonna go with E. Protected elements in a package? That's like putting a lock on your front door and leaving the key under the mat!

Yeah, that's a good point. I think I'll go with E too.

E) Protected elements are not allowed in a package.

You know what they say, 'if it's not broke, don't fix it.' I'm going with A. A list of elements in a package body? That's just common sense.

Pilar 2 years ago

Nah, man, it's gotta be B. How can you have a class without a visibility? That's like having a superhero without a cape!

I agree with you, it has to be B. Classone is missing a visibility.
