创造未来

Created: November-22, 2018

import scala.concurrent.Future
import scala.concurrent.ExecutionContext.Implicits.global

object FutureDivider {
    def divide(a: Int, b: Int): Future[Int] = Future {
        // Note that this is integer division.
        a / b
    }
}

很简单，divide 方法创建一个 Future，它将使用 a over b 的商来解析。
