Hi everyone,
Are there interaction diagrams with forks/if-logic on the exam?
Thanks

Yes. And even iterations in interaction diagram are also part of exam.

Thanks.
I have a question about the recursion symbol in a sequence diagram.
I have a C background and I think of recursion as a method calling itself x number of times. The UML definition I have read says recurision is an object calling itself, this seems rather vague? Are you suppose to show a recursive symbol in your sequence diagram any time an object calls itself?
Thanks

I have read another definition that states you show recursion when a method calls itself.
It seems like the symbol is somewhat conceptual, in that you want someway of showing recursion. The sequence diagram is usually for showing how objects interact with each other not with themselves.
