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

How to find Union of Two Sets in Kotlin ?

Answer

To find the union of two sets in Kotlin, you can use the union operator or the union function.


✐ Examples

1 Union of Two Sets using Union Operator

In this example,

  1. We create two sets named set1 and set2.
  2. We use the union operator + to find the union of set1 and set2 and store the result in unionSet.

Kotlin Program

fun main() {
    val set1 = setOf(1, 2, 3)
    val set2 = setOf(3, 4, 5)
    val unionSet = set1 + set2
    println("Union of set1 and set2: $unionSet")
}

Output

Union of set1 and set2: [1, 2, 3, 4, 5]

2 Union of Two Sets using Union Function

In this example,

  1. We create two sets named set1 and set2.
  2. We use the union() function to find the union of set1 and set2 and store the result in unionSet.

Kotlin Program

fun main() {
    val set1 = setOf(1, 2, 3)
    val set2 = setOf(3, 4, 5)
    val unionSet = set1.union(set2)
    println("Union of set1 and set2: $unionSet")
}

Output

Union of set1 and set2: [1, 2, 3, 4, 5]
