kotlin class constructor 构造方法的使用

6 kotlin之class

kotlin的class比Java更简洁,构造方法,使用更方便,类似于方法直接写上参数即可

class Player {
    var name: String = ""

    constructor(fullName: String) {
        this.name = fullName

    }

    fun sayHello() {
        println("hello $name")
    }

    fun getAge(): Int {
        return 18
    }
}

class Match(private val home: String,
            private val away: String, private val data: String) {
    fun getMatchInfo(): String {
        return "$away- $home -$data"
    }
}

fun main() {
    val player = Player("handsome")
    player.sayHello()
    println("${player.name} is ${player.getAge()}")

    val math = Match("China", "building",
            "20200522")
    println(math.getMatchInfo())
}
