27.3.3. Abstract Factory Pattern

Try these first

1. 1.

   Define the Abstract Factory Pattern in your own words.

   Hint

   Think about how it separates object creation from usage.

2. 2.

   What is a concrete class?

   Hint

   Consider the opposite of an abstract class.

3. 3.

   What does the Abstract Factory Pattern allow you to do?

   • Define the concrete classes of objects to be created

   • Create a single type of object only

   Hint

   Recall the purpose of the pattern.

4. 4.

   • True

5. 5.

   Consider a software system that supports multiple payment gateways. Design an Abstract Factory Pattern to manage these payment methods. Include at least two payment types.

   Hint

   Think about how varying payment methods rely on a common interface.

6. 6.

   Analyze a commonly used software application (like a text editor) and describe how the Abstract Factory Pattern could improve its architecture. What differences would you expect?

   Hint

   Focus on the architecture and user interface elements.
