有沒有辦法覆蓋默認對象打印

Question

我想在scala中打印一個類。定義如下：

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

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

我想打印沿着線的東西來安慰：

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

有沒有辦法，我可以重寫ToString運營商一樣，你可以在Java中，以實現任何方式這還是我做的方法，如：

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

並調用

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

Answer 1

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