Additional Notes
How would you explain a common mistake when implementing the Builder pattern in an interview?
Track: Java
Topic: Software Architecture
Focus: Builder Pattern
Java: Builder Pattern
Answer
A common mistake is not validating the builder's state before building the object.
When building a `Payment` object, failing to check for necessary fields like payment method or amount can lead to runtime errors. Always validate these fields in the build() method to ensure the object is correctly constructed.
