如何在scala代码中实现多线程？

class MyThread extends Thread {
  override def run(): Unit = {
    // 线程执行逻辑
  }
}

// 创建并启动线程
val thread = new MyThread()
thread.start()

import akka.actor._

class MyActor extends Actor {
  def receive: Receive = {
    case message: String =>
      // 处理消息
  }
}

// 创建Actor系统
val system = ActorSystem("MySystem")
// 创建并启动Actor
val actor = system.actorOf(Props[MyActor], "myActor")
// 发送消息给Actor
actor ! "Hello"

import scala.concurrent._
import ExecutionContext.Implicits.global

// 创建并发任务
val task = Future {
  // 异步执行的任务
  "Result"
}

// 处理任务结果
task.onComplete {
  case Success(result) =>
    // 处理成功结果
  case Failure(exception) =>
    // 处理异常情况
}
