Answer
Implement checks in the build() method to enforce preconditions.
For instance, when constructing an `Invoice`, you should check if the total amount and date are properly set. The build() method should validate these fields and throw an exception if any are missing or invalid, ensuring the `Invoice` is complete and correct.
