what is aggregation and segregation in java

[Jeanne Boyarsky]

Sitaram,
Aggregation is having a bunch of objects in another object. For example, you aggregate a bunch of items in an ArrayList.

Segregation typically deals with separation of concerns. For example, you segregate presentation from the view in MVC.

When a request comes, we separate it into several subsets that can be executed in a serial or parallel manner, which finally gives a response to the user.
The separation operation is called segregation
And the operation of gathering the results is called aggregation

[Campbell Ritchie]

I am afraid that isn't the usual object‑oriented definition of aggregation. See Jeanne's post above.
