Scala基本语法（二）

Point 1：Actor

package com.scala.learnimport scala.actors._, Actor._object Actor1 {  def main(args: Array[String]) = {    val badActor =      actor {        while (true) { //nexttpule          receive {            case msg =>              println(msg);              reply("gagagagag");          }        }      }    println("Do ya feel lucky, punk?");//    println(badActor ! "dddddddddddddd"); //! 异步发送消息    //这里的println打印的是返回来的值，也就是reply中的值    println(badActor ! "mmmmmmmmmmmmmmm");  }}

Point 2：

package com.scala.learnimport scala.actors._, Actor._object Actor2 {  case class Speak(line: String)  case class Gesture(bodyPart: String, action: String)  case class NegotiateNewContract()  def main(args: Array[String]) =    {      val badActor =        actor {          receive {            case NegotiateNewContract =>              println("I won't do it for less than $1 million!")            case Speak(line) =>              println(line)            case Gesture(bodyPart, action) =>              println("(" + action + "s " + bodyPart + ")")            case _ =>              println("Huh? I'll be in my trailer.")          }        }//      badActor ! NegotiateNewContract//      badActor ! Speak("Do ya feel lucky, punk?")//      badActor ! Gesture("face", "grimaces")//      badActor ! Speak("Well, do ya?")      badActor ! "Well, do ya?"      Thread.sleep(3000);    }} 

Point 3：

package com.scala.learnimport scala.actors._, Actor._object Actor3 {      case class Speak(line : String);        case class Gesture(bodyPart : String, action : String);        case class NegotiateNewContract();        case class ThatsAWrap();        def main(args : Array[String]) =        {          val badActor =            actor            {              var done = false             while (! done)  //相当于true            {                receive                {                  case NegotiateNewContract =>                    System.out.println("I won't do it for less than $1 million!")                  case Speak(line) =>                    System.out.println(line)                  case Gesture(bodyPart, action) =>                    System.out.println("(" + action + "s " + bodyPart + ")")                  case ThatsAWrap =>                    System.out.println("Great cast party, everybody! See ya!")                  done = true                 case _ =>                    System.out.println("Huh? I'll be in my trailer.")                }              }            }          badActor ! NegotiateNewContract//        badActor ! Speak("Do ya feel lucky, punk?")  //        badActor ! Gesture("face", "grimaces")  //        badActor ! Speak("Well, do ya?")  //        badActor ! ThatsAWrap      }  }
