Design Pattern : Builder

Hi Lionel, thanks for interacting.

Both patterns belong to the family of object construction patterns. The Factory pattern is useful when you want to create different types of objects from a class (a dedicated factory). The Factory class generally relies on conditions to determine which type of object to build.

It's the expression "different types of objects" that marks the difference between the two patterns. In the case of the Builder, built objects are always of the same type.
