How to create a Set of integers in Kotlin

How to create a Set of integers in Kotlin ?

Answer

To create a set of integers in Kotlin, you can use the setOf() function or setOf constructor.


✐ Examples

1 Create a Set of Integers using setOf() function

In this example,

  1. We use the setOf() function to create a set of integers.

Kotlin Program

val intSet = setOf(1, 2, 3, 4, 5)
println("Set of integers: $intSet")

Output

Set of integers: [1, 2, 3, 4, 5]

2 Create a Set of Integers using setOf constructor

In this example,

  1. We use the setOf constructor to create a set of integers.

Kotlin Program

val intSet = setOf<Int>(1, 2, 3, 4, 5)
println("Set of integers: $intSet")

Output

Set of integers: [1, 2, 3, 4, 5]

Summary

In this tutorial, we learned How to create a Set of integers in Kotlin language with well detailed examples.
