Aggregation means one object is the owner of another object. Composition means one object is contained in another object .

The composition is stronger than Aggregation . In Short, a relationship between two objects is referred to as an association, and an association is known as composition when one object owns another while an association is known as aggregation when one object uses another object.16 Eyl 2021

Aggregation and Composition are subsets of association meaning they are specific cases of association . In both aggregation and composition object of one class “owns” object of another class. But there is a subtle difference: Aggregation implies a relationship where the child can exist independently of the parent.
