Scala 一些便捷文本操作

Scala WordCount

def wordCount(){ //scala worldcountS     val map = scala.collection.mutable.Map[String,Int]()     val in = Source.fromFile("/home/yc/Desktop/1").getLines()     for(i<-in) map(i) = map.getOrElse(i, 0)+1     println(map.mkString("\n"))   }

Scala 文本倒序输出

def test2{  //倒序输出文本   val in = Source.fromFile("/home/yc/Desktop/1").getLines()   val result = in.toArray.reverse   val out = new PrintWriter("/home/yc/Desktop/2")   result.foreach { p => out.println(p) }   out.close() }
