kotlin mutableMapをSequenceに変換するサンプル
環境
java 19.0.1
kotlin 1.7.20
構文
map名.asSequence()
mutableMapをSequenceに変換するには、「asSequence」関数を使用します。
使用例
fun main() {
val m = mutableMapOf('a' to 11, 'b' to 22, 'c' to 53)
var t = m.asSequence()
println( t is Set<*> )
println( t is Map<*,*> )
println( t is Sequence<*> )
}
fun main() {
val m = mutableMapOf('a' to 11, 'b' to 22, 'c' to 53)
var t = m.asSequence()
println( t is Set<*> )
println( t is Map<*,*> )
println( t is Sequence<*> )
}
fun main() {
val m = mutableMapOf('a' to 11, 'b' to 22, 'c' to 53)
var t = m.asSequence()
println( t is Set<*> )
println( t is Map<*,*> )
println( t is Sequence<*> )
}
実行結果
false
false
true
