mutableSetOf
Returns an empty new MutableSet.
The returned set preserves the element iteration order.
import kotlin.test.*
fun main(args: Array<String>) {
//sampleStart
val set = mutableSetOf<Int>()
println("set.isEmpty() is ${set.isEmpty()}") // true
set.add(1)
set.add(2)
set.add(1)
println(set) // [1, 2]
//sampleEnd
}
Returns a new MutableSet with the given elements. Elements of the set are iterated in the order they were specified.
import kotlin.test.*
fun main(args: Array<String>) {
//sampleStart
val set = mutableSetOf(1, 2, 3)
println(set) // [1, 2, 3]
set.remove(3)
set += listOf(4, 5)
println(set) // [1, 2, 4, 5]
//sampleEnd
