What are the advantages of a Kotlin data class and its functions?
Tests knowledge of Kotlin's idiomatic features. A good answer explains the main advantage (boilerplate reduction), lists generated functions like toString() and equals(), and describes copy() for immutable state updates.
This tests your grasp of Kotlin's idiomatic features for data-holding classes. A strong answer first states the main advantage: automatic boilerplate generation (`toString`, `equals`, etc.). Then, list key generated functions. Finally, explain `copy()`'s practical use for immutability, like updating a user state object for a UI refresh without direct mutation. A red flag is just listing functions without explaining `copy()`'s role in managing state, which is a core concept in modern Android development.
