scala本地wordcount的程序编写

主要是在本地编写一个计算文件中单词出现次数的工具，一下是代码：

import scala.actors.{Future, Actor}
import scala.collection.mutable
import scala.collection.mutable.{ListBuffer, ArrayBuffer}
import scala.io.Source

/**
* mhc
* Created by Administrator on 2016/5/12.
*/

case class startTask(fileName: String)

case class stopTask()

case class resultSet(result: Map[String, Int])

class Task extends Actor {
override def act(): Unit = {
loop {
react {
case startTask(fileName: String) => {
// 开始任务
val lines = Source.fromFile(fileName).mkString
val arr = lines.split("\r\n")
val result = arr.flatMap(_.split(" ")).map((_, 1)).groupBy(_._1).mapValues(_.length)
sender ! resultSet(result)
}
case stopTask => {
exit()
}

}
}
}
}

object Task {
def main(args: Array[String]) {
val replySet = new mutable.HashSet[Future[Any]]
var list = new ListBuffer[resultSet]
val files = Array("D://words.txt", "D://newword.txt")
val task = new Task
task.start()
for (s <- 0 until files.length) {
replySet += (task !! startTask(files(s))) // 发送消息
}
for (set <- replySet) {
list += set.apply().asInstanceOf[resultSet]
}
val result = list.map(_.result).flatten.groupBy(_._1).mapValues(x => x.foldLeft(0)(_ + _._2))
println(result)

}
}
