Multiple choiceHardchapter-13-curatedpremiumsoftware-architecturebuilder-pattern
Answer and explanation
Correct answer
B. Ensure all fields are final and private.
Why
To ensure immutability, all fields of the class should be declared as final and private. This prevents changes to the fields after the object is constructed, ensuring the object's state cannot be altered.
