UML Class 图：Object 通过构造函数关系？

Question

Suppose I have a class like this in Java:

public class ClassA{
     public ClassA(ClassB b){
          // do some operations or get some values etc. from ClassB b

ClassB is passed to ClassA through its constructor. (not a method) Is this relationship considered a dependency or some form of association? If we were to assume that there is no ClassB attribute in ClassA.

Answer 1

This would normally be a dependency or 'uses' relationship. Association implies a 'has-a' relationship.

Answer 2

If an instance of ClassA keeps the passed instance of ClassB, then model as an association. Otherwise, model as a dependency.
