Question

我正试图用斜体印刷一个班子。定义如下:

class Player(balance : Int, player_num :Int ){
    var curHand = new ArrayBuffer[Int]()
    var sum = 0

    def method1()={
        ....
    }
}

我想用以下几条文字印制:

var player1 = new Player(100,1)
println(player1)

是否有任何办法可以凌驾于你在ava中所能做的操作者之上,以达到这一目的,或者我不得不采取这样一种方法:

def print(){
    println("balance " + balance + "Player number" + player_num)
}

电话

var player1 = new Player(100,1)
player1.print()

Answer 1

override def toString = "balance " + balance + " Player number " + player_num
