Question

I need to set a variable depending on a condition. But since variables are immutable, I find myself in a sticky situation having to repeat code. What I’d like to do is:

def doSomething(x:Int):Int = {
  if(x==1){
    val player="Andy"
  } else {
    val player="Rob"
  }
  getSomeValue(player) // Another function
}

But the variable “player” is no longer in scope. Only way I see is to call the function “getSomeValue” in both the condition blocks, but that’s not something I’d like to do. How do I get around this using immutable variables?

Answer 1

def doSomething(x:Int):Int = {
  val player = if(x==1){
    "Andy"
  } else {
    "Rob"
  }
  getSomeValue(player)
}
