What is the difference between the Abstract Factory and Builder patterns?

What is the difference between the Abstract Factory and Builder patterns?

The Abstract Factory pattern provides an interface for creating families of related or dependent objects without specifying their concrete classes. In contrast, the Builder pattern focuses on constructing a complex object step by step, allowing for more control over the construction process.

Can you give me an example of when to use each pattern?

Sure! Use the Abstract Factory when you need to create multiple related objects, like UI components for different platforms. Use the Builder pattern when you want to construct a complex object, like a meal with various courses, where the order of creation matters.

What are the advantages of using these patterns?

The Abstract Factory promotes loose coupling and makes it easier to introduce new products. The Builder pattern enhances readability and allows for more flexible object creation.

Are there any drawbacks to using these patterns?

Yes, both patterns can introduce complexity. The Abstract Factory can lead to a proliferation of classes, while the Builder pattern may require additional code to manage the construction process.
