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.

hth.
