Data Classes vs. Tuples

Data Classes vs. Tuples

Explore the advantages of data classes over tuples and understand when and how to use each for better code clarity and error prevention.

We'll cover the following...

The Pair and Triple data classes

Data classes offer more than what is generally provided by tuplesIn programming, a tuple is an ordered collection of elements. In Kotlin, data classes like Pair and Triple function as tuples, offering additional features and replacing traditional tuple usage.. They have replaced tuples in Kotlin since they’re considered better practice. The only tuples that are left are Pair and Triple, but these are actually data classes under the hood

Press + to interact
data class Pair<out A, out B>(
   val first: A,
   val second: B
) : java.io.Serializable {
   override fun toString(): String =
       "($first, $second)"
}
data class Triple<out A, out B, out C>(
   val first: A,
   val second: B,
   val third: C
) : java.io.Serializable {
   override fun toString(): String =
       "($first, $second, $third)"
}
