Additional Notes
How would you explain a common pitfall when using the Builder pattern in an interview?
Track: Java
Topic: Software Architecture
Focus: Builder Pattern
Java: Builder Pattern
Answer
Forgetting to call the build() method. Frame the concept in practical terms so you can explain it during interview discussion.
A common mistake is neglecting to call the build() method at the end of the chain, resulting in an incomplete object. This can lead to unexpected behavior or runtime errors. For example, if you forget `.build()` in `Order order = new OrderBuilder().withProduct("Laptop")`, you will not get a fully constructed 'Order' object.
