i am a beginner

i am drawing a classs diagram.

we should use dependency when a method of class A use the paremater which is class B.


should i use association when some attributes' type of class A are class B?


if class A have two attributes: ApplyPerson & ConfirmPerson.
they are instances of class User,
should i use two associations between the class A and the class User?

1/ Yes. If A has an attribute of type B, then you have an association from A to B.

2/ Yes. 2 different attributes are shown as 2 links. It would not be the case with a collection of users. A collection would be shown with a single link but a multiplicity greater than one (usually a "*").
