Answer from AI

Data classes in Kotlin (Android) are convenient for storing data, but there are situations where their use is not advisable:

  • When the object contains complex logic or behavior, not just data.
  • If the class needs to be mutable and have complex states that do not fit the data class concept.
  • When controlling inheritance is important, as data classes do not support inheritance from other classes.
  • If memory and performance optimization are important, since data classes generate additional methods (equals, hashCode, toString), which can be excessive.

For example, for classes with business logic, it is better to use regular classes rather than data classes.
