Q15. Creational patterns focus on the ___ of objects.
- Creation
- Composition
- Representation
- All of the mentioned above
Answer: D) All of the mentioned above
Explanation:
Creational patterns are concerned with the "creation, composition, and representation" of objects, and they provide techniques that make object instantiation inside a system easier, as well as "constraints on the type and quantity of objects that can be generated within a system."
Q16. Structural patterns focus on problems and solutions associated with how ___ are organized
