Question - What is a data class in Kotlin?
Answer -
In Kotlin, a data class is a class whose main purpose is to hold data. It is marked as "data".
Syntax:
data class User(val name: String, val age: Int)
The data classes must have to fulfill the following requirements to ensure consistency and meaningful behavior of the generated code:
- The primary constructor must have at least one parameter
- , and all primary constructor parameters need to be marked as val or var.
- Data classes cannot be abstract, open, sealed, or inner.
