I have a question which has been explained in many ways , but still has not made me clear.
- What is creating of objects by "Object composition" in terms of abstract factory pattern ?
It seems like both the patterns use inheritance to create objects.

2What are you reading that talks about this? – Vaughn Cato Jun 02 '13 at 18:13

The interface of an abstract factory, or a class with a factory method may very well be defined in an interface and therefore does not have to use inheritance to create objects. – Lorentz Vedeler Jun 02 '13 at 18:31

Mr Vaughn, I read this while trying to understand Factory method and abstract factory pattern. – Chandan Jun 03 '13 at 09:38

Object composition means the object is composed of something. It's basically the strategy pattern, making the two objects have a "has-a" relationship, rather than an "is-a" relationship (as with straight inheritance).

I know that each object in the family of related objects created as part of abstract factory can be created by a factory method. But I did not understand why strategy pattern comes into picture. – Chandan Jun 03 '13 at 04:24
