Introduction
The Builder pattern constructs complex objects step by step, allowing for customization while keeping code organized and readable.
Real-Life Example
Building a pizza: You don’t want to specify each detail (dough, sauce, toppings) in a single constructor call. Instead, you add ingredients step by step, ensuring flexibility and clarity.
Pros
Improves readability and maintainability for complex objects.
Allows step-by-step object construction with optional parameters.
Prevents “constructor hell” when dealing with multiple parameters.
Cons
Requires extra code to define the builder class.
May introduce unnecessary complexity for simple objects.
When to Use It
When dealing with objects with many optional or configurable parameters.
When the construction process should be clear and structured.
Avoid for simple objects where a constructor is sufficient.
Conclusion
The Builder pattern shines when managing complex object creation but should be avoided when a simpler approach will do.
