How does polymorphism benefit code maintainability in Java?
Multiple choiceEasychapter-5-curatedpremiumooppolymorphism
Answer and explanation
Correct answer
D. By allowing objects to be accessed through references of their interface or superclass type
Why
Polymorphism allows objects to be accessed through references of their interface or superclass type, which reduces the need to know the exact class type. This simplifies code maintenance and increases flexibility by allowing the implementation to change without affecting the caller.
