I'm aware of the conceptual differences between Aggregation and Composition. Can someone tell me the implementation difference in Java between them with examples?

Aggregation vs Composition
Aggregation implies a relationship where the child can exist independently of the parent. For example, Bank and Employee, delete the Bank and the Employee still exist.
whereas Composition implies a relationship where the child cannot exist independent of the parent. Example: Human and heart, heart don’t exist separate to a Human.
Aggregation relation is “has-a” and composition is “part-of” relation.
Composition is a strong Association whereas Aggregation is a weak Association.
