How to find Intersection of Two Sets in Kotlin - Step by Step Examples

How to find Intersection of Two Sets in Kotlin ?

Answer

To find the intersection of two sets in Kotlin, you can use the intersect method provided by the Set class.


✐ Examples

1 Find Intersection of Two Sets using intersect Method

In this example,

  1. We create two sets named set1 and set2.
  2. We call the intersect method on set1 with set2 as an argument.

Kotlin Program

val set1 = setOf(1, 2, 3, 4, 5)
val set2 = setOf(4, 5, 6, 7, 8)
val intersection = set1.intersect(set2)
println("Intersection: $intersection")

Output

Intersection: [4, 5]

2 Find Intersection of Two Sets using & Operator

In this example,

  1. We create two sets named set1 and set2.
  2. We use the & operator to find the intersection of set1 and set2.

Kotlin Program

val set1 = setOf(1, 2, 3, 4, 5)
val set2 = setOf(4, 5, 6, 7, 8)
val intersection = set1 & set2
println("Intersection: $intersection")

Output

Intersection: [4, 5]

Summary

In this tutorial, we learned How to find Intersection of Two Sets in Kotlin language with well detailed examples.
