class create another class and associate with it later delete it, how to show it in UML class diagram?

Question

Let A and B are classes.

• A is the class which is responsible for creating class B
• after creating of ,B A is associated with B
• after some time class A is Delete class B

as a example for above scenario consider there is project manager and he is responsible for creating,editing,deleting project from the system

i know class A create class b can show in UML as dependency relationship

i have two questions

1. how to represent class delete another class

2. so there is both association and dependency relationship from A to B. How should this relationship be demonstrated on UML class diagram? Should I use booth association(straight line) and dependency(dashed line) relationships

Answer 1

You simply put a multiplicity of 0..1 towards the association to B. And that's it. No extra dependency.
