* Scala multi-threaded combat

* 1: Development environment: Scala IDE (version: 2.11.8) integrated development environment

* 2: Reference jar package: Scala-actors.jar,scala-actors-migration.jar

* 3: This instance uses Scala pattern matching and Scala multithreaded use technology

* Scala Multithreading concurrent Invocation method is:

* Companion Class: Class XXX extends Actor

* def Act () {

* while (true) {

* receive{

* case

* case

*    }

*    }

* Companion Method: Object () {

* Instantiate XXX

* Call the Start () method

Object Helloactor {

def main (args:array[string]): Unit = {

Val helloactor = new Helloactor

Calling Scala multithreaded methods

Helloactor.start ()

Val hellobackactor = new Hellobackactor (helloactor)

Hellobackactor.start ()

var counter = 0

/*while (True) {

Helloactor! "Wow" + counter

Counter + = 1

Thread.Sleep (3000)

}*/

Helloactor! Hello ("Spark", "spark means Dollars")

}

}

Case Class Hello (name:string, content:string, Sender:actor)

Case Class Helloback (name:string, content:string, Sender:actor)

Class Helloactor extends actor{

var counter = 0

Def Act () {

while (true) {

Receive {

Case content:string = println ("Message:" + content)

Case Hello (name, content,sender) + = {

println ("Helloactor:" + "Name:" + name + "Content:" + content + counter)

Counter + = 1

Thread.Sleep (3000)

Sender! Helloback (name, Content+counter, this)

}

}

}

}

}

Class Hellobackactor (Val helloactor:actor) extends actor{

var counter = 0

Def Act () {

Helloactor! Hello ("Spark", "Love Was Here", this)

while (true) {

Receive {

Case content:string = println ("Message:" + content)

Case Helloback (name, content,sender) + = {

println ("Hellobackactor:" + "Name:" + name + "Content:" + content + counter)

Counter + = 1

Thread.Sleep (3000)

Sender! Hello (name, Content+counter, this)

}

}

}

}

}

The result of the operation is:

HelloActor:name:Spark Content:love is HERE0

HelloBackActor:name:Spark Content:love is Here10

HelloActor:name:Spark Content:love is here111

HelloBackActor:name:Spark Content:love is here1121

HelloActor:name:Spark Content:love is here11222

HelloBackActor:name:Spark Content:love is here112232

HelloActor:name:Spark Content:love is here1122333

HelloBackActor:name:Spark Content:love is here11223343
