Tuple

Scala中Tuple为单个键值对。

object TupleTest {
    def main(args: Array[String]): Unit = {
        val t = ("Lebron" -> 23)
        println(t._1, t._2) //访问key和value
        //zip操作
        val names = Array("Lebron", "Rondo", "Ball")
        val numbs = Array(23, 9, 0)
        //返回一个元素类型为tuple的数组
        val tuples = names.zip(numbs)
        for ((name, number) <- tuples) {
            println(name, number)
        }
    }
}
