Scala-柯里化

Scala-柯里化

代码如下：

object ScalaInAction {
     // 这三个代码是等价的
    def mul(x:Int,y:Int) = x * y
    def mul(x:Int) = (y:Int) => x * y
    def mul1(x:Int)(y:Int) = x * y

    def main(args: Array[String]): Unit = {
        println(mul(5 ,6))
        println(mul(5)(6))
        println(mul1(5)(6))
    }
}

结果如下
