Multiple choiceEasychapter-3-curatedpremiumoopimmutability-basics
Answer and explanation

Declaring fields as private enforces encapsulation by preventing external classes from accessing and modifying them directly. This allows the class to control how its internal state is accessed and modified, thus maintaining its integrity.
