class diagram - Does association in UML associate objects or classes? -
on wikipedia, i'm reading association relationship instance level relationship talking relationship between objects of 2 classes.
when draw class diagram, why use association on class elements or blocks rather objects? , there class level relationships again use class elements. since don't have way show if talking objects or classes find confusing. example: i've heard people saying "associate these 2 classes" doesn't sound wrong?
links
associations
objects
classes
.
a class abstraction describes many specific objects. similarly, association abstraction describes many links between objects.
so statement
an association relationship instance level relationship
isn't strictly correct because mixes abstraction (association relationship) instances represents.
