How can I handle errors in Scala Futures?

In Scala, you can handle errors in Futures using methods like recover, recoverWith, and onComplete. Would you like examples?

Yes, please provide an example using recover.

Sure! Here's a simple example:

val future = Future { throw new RuntimeException("Error!") }
val recoveredFuture = future.recover { case _: RuntimeException => "Recovered from error!" }

This will return "Recovered from error!" instead of failing.

What about using onComplete?

Using onComplete, you can handle both success and failure cases. Here's an example:

future.onComplete {
  case Success(value) => println(s"Success: $value")
  case Failure(exception) => println(s"Failed with: $exception")
}

This will print the success value or the exception.
