Scala 函数柯里化

1、代码

package com.yy.base

/**
* 函数柯里化
*/
object CurringFuncTest {
def main(args: Array[String]): Unit = {

//正常定义1
def multiple1(x:Int,y:Int) = x*y
println(multiple1(2,3))
//其中一个函数作为返回值
def multiple2(x:Int)=(y:Int)=>x*y
println(multiple2(3)(4))

//柯里化
def multiple3AfterCurring(x:Int)(y:Int) = x*y
println(multiple3AfterCurring(4)(5)) //必须传递两个参数，否则编译报错

val a = Array("XX","YY")
val b = Array("xx","yy")
println(a.corresponds(b)(_.equalsIgnoreCase(_)))
}
