运行环境：Jdk1.7、scala-2.10.4 package study /** * Document:本类作用---->拆分List * User: yangjf * Date: 2016/8/14 8:57 */ object TestArrays { def main(args: Array[String]) { val lists=List(12,34,5,19,56,23,16) val end: (List[Int], List[Int]) =lists.partition(_>20) println("获得新元祖："+end) val maps=Map(1->"tom",2->"jim",3->"cassie",4->"hello",5->"worldss") val ends1: (Map[Int, String], Map[Int, String]) =maps.partition(_._2.length>3) println("获取新元祖:"+ends1) val sets=Set(23,12,45,21,56,62,55,23) val setends=sets.partition(_>40) println("获取新元祖:"+setends) } } 结果：获得新元祖：(List(34, 56, 23),List(12, 5, 19, 16)) 获取新元祖:(Map(5 -> worldss, 3 -> cassie, 4 -> hello),Map(1 -> tom, 2 -> jim)) 获取新元祖:(Set(56, 45, 55, 62),Set(21, 12, 23))
