有没有办法覆盖默认对象打印

Question

我想在scala中打印一个类。定义如下：

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

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

我想打印沿着线的东西来安慰：

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

有没有办法，我可以重写ToString运营商一样，你可以在Java中，以实现任何方式这还是我做的方法，如：

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

并调用

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

Answer 1

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