Why do teams use private access modifiers for fields in a Java class in production code?
Multiple choiceEasychapter-3-curatedpremiumcore-javacode-reading-and-state-safety
Answer and explanation
Correct answer
B. It prevents external modification of fields.
Why
Using private access modifiers restricts field access to within the class itself, thus preventing external classes from modifying the fields directly. This supports encapsulation by keeping the object's internal representation hidden.
