Perform more than one operation in scala's foreach?

Question

Let's say I have this ListBuffer that I am filling in a scala foreach like the following:

Tokens.foreach(t => tokens+=new Token(t._1.toString()))

i am wondering whether it is possible to perform another operation at the same time for-example adding to a string something like:

Tokens.foreach(t => tokens+=new Token(t._1.toString()), posTagString+=t._2.toString())

the 2nd example results in a "too many arguments (2) for method foreach" error. Is there a way to do this or shall I just stick too the form of:

   for(x<-Tokens){



    }

Answer 1

try this? :

Tokens.foreach{t => 
  tokens+=new Token(t._1.toString())
  posTagString+=t._2.toString()
}
