Scala 是否有方法覆盖默认对象打印

我正在尝试用scala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()={
        ....
    }
}

我想打印到console，内容大致如下：

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

有没有什么方法可以像java中一样重写toString操作符来实现这一点，或者我必须创建如下方法：

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

打电话

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

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