kotlin mutableMapをPropertiesに変換するサンプル
環境
Windows11 pro 64bit
java 19.0.1
kotlin 1.7.20-release-201
構文
mutableMap名.toProperties()
mutableMapをPropertiesに変換するには、「toProperties」を利用します。
使用例
fun main() {
val m = mutableMapOf("tokyo" to "S", "ooska" to "T", "fukuoka" to "R" )
println( m.toProperties() )
println( m.toProperties().javaClass )
}
fun main() {
val m = mutableMapOf("tokyo" to "S", "ooska" to "T", "fukuoka" to "R" )
println( m.toProperties() )
println( m.toProperties().javaClass )
}
fun main() {
val m = mutableMapOf("tokyo" to "S", "ooska" to "T", "fukuoka" to "R" )
println( m.toProperties() )
println( m.toProperties().javaClass )
}
実行結果
{tokyo=S, fukuoka=R, ooska=T}
class java.util.Properties
