日記

WoTでホリデーイベントが始まったのでシュッとボックス買った．去年は無課金ですべてのステージをクリアしたが結構時間がかかった．今回はもう8割ぐらい終わったので金の弾丸すごい．

今日書いたコード

fun main() {
    val entrees = mutableListOf<String>()
    println("Entrees: $entrees")
    println("Add noodles: ${entrees.add("noodles")}")
    println("Entrees: $entrees")
    println("Add spaghetti: ${entrees.add("spaghetti")}")
    println("Entrees: $entrees")
    val moreItems = listOf("ravioli", "lasagna", "fettuccine")
    println("Add list: ${entrees.addAll(moreItems)}")
    println("Entrees: $entrees")
    println("Remove spaghetti: ${entrees.remove("spaghetti")}")
    println("Entrees: $entrees")
    println("Remove item that doesn't exist: ${entrees.remove("rice")}")
    println("Entrees: $entrees")
    println("Remove first element: ${entrees.removeAt(0)}")
    println("Entrees: $entrees")
    entrees.clear()
    println("Entrees: $entrees")
    println("Empty? ${entrees.isEmpty()}")
}

Entrees: []
Add noodles: true
Entrees: [noodles]
Add spaghetti: true
Entrees: [noodles, spaghetti]
Add list: true
Entrees: [noodles, spaghetti, ravioli, lasagna, fettuccine]
Remove spaghetti: true
Entrees: [noodles, ravioli, lasagna, fettuccine]
Remove item that doesn't exist: false
Entrees: [noodles, ravioli, lasagna, fettuccine]
Remove first element: noodles
Entrees: [ravioli, lasagna, fettuccine]
Entrees: []
Empty? true

感想

今日はMutableListを色々する回だった．特に面白いメソッドはない．
