Association ,Compostion and Aggregation are one of teh pillars of OOPs
Composition:when twoobjects have same life-time (Person+heart/Customer+address) without one there is no existance of other
Aggregation:when 2 objects have different-life time(Person+shirt+pant/Customer+logging)
Association: is a relationship between two classes, where one class use another.
