How can I handle errors in concurrent Scala applications?

In Scala, you can handle errors in concurrent applications using constructs like Future and Try. Would you like an example?

Yes, please provide an example of using Future and Try together.

Sure! You can wrap your Future in a Try to catch exceptions. Here's a simple example:

import scala.concurrent.Future
import scala.util.{Failure, Success, Try}

val futureResult: Future[Int] = Future { 
  // some computation that might fail
  if (Math.random() > 0.5) throw new RuntimeException("Failed!")
  42
}

futureResult.onComplete { 
  case Success(value) => println(s"Result: $value")
  case Failure(exception) => println(s"Error: ${exception.getMessage}")
}

What if I want to handle multiple Futures at once?

You can use Future.sequence to handle multiple Futures. It will return a Future of a sequence. If any Future fails, the whole sequence fails.
