環境
Windows10 Home 64bit
Java 19.0.1
Kotlin 1.7.20-release-201
書式
val 変数名 =mutableSetOf(要素1,要素2,…
変数名.remove(値)
removeメソッドを使ってmutableSetの値を削除します。
使用例
fun main() {
val cft = mutableSetOf( "study", "skill", "become", "smart", "arkgame" )
println( cft )
cft.remove("arkgame")
println( cft )
cft.remove("smart")
println( cft )
}
fun main() {
val cft = mutableSetOf( "study", "skill", "become", "smart", "arkgame" )
println( cft )
cft.remove("arkgame")
println( cft )
cft.remove("smart")
println( cft )
}
fun main() {
val cft = mutableSetOf( "study", "skill", "become", "smart", "arkgame" )
println( cft )
cft.remove("arkgame")
println( cft )
cft.remove("smart")
println( cft )
}
実行結果
[study, skill, become, smart, arkgame]
[study, skill, become, smart]
[study, skill, become]
