How can a class ensure that its objects remain immutable?
Multiple choiceMediumchapter-3-curatedpremiumoopcontrolled-mutation
Answer and explanation
Correct answer
B. Make all fields final and provide no setters.
Why
To create an immutable class, all fields should be declared as 'final' and initialized via a constructor, with no setters provided. This ensures that once an object is created, its state cannot change.
