Aggregation and containment in the Programming

Question

Illustrate the basic difference between Aggregation and containment in the Programming?

Answer 1

Aggregation is a relationship between the whole and a part. We can add or subtract some of the properties in the part (or slave) side. It won’t influence the whole part.

Best illustration is Car that comprises the wheels and some additional parts. Even although the parts are not there we can call it as car.

However, in the case of containment the entire part is influenced when the part in that got influenced. The human body is an apt instance for this relationship. Whenever the whole body dies the parts (heart and so on) are died.
