Problem Statement
Compare the Factory Method and Builder patterns and describe scenarios where each is more appropriate.
Explanation
The Factory Method pattern is about defining an interface for creating an object but letting subclasses decide which class to instantiate. It is useful when you want to vary the concrete implementation based on runtime conditions. /n/n The Builder pattern, on the other hand, is about constructing a complex object step-by-step, where you might want optional parameters, fluent interface, or different representations of the same product. /n/n Use a Factory when you have a single method that returns varied subclasses; use a Builder when you need to build complex objects with many options or deviate from simple constructors.
