Scala Tuple Deconstruction

Question

I am new to Scala, and ran across a small hiccup that has been annoying me.

Initializing two vars in parallel works great: var (x,y) = (1,2)

How

Answer 1

Scala has 2 types of variables: vals and vars. Vals are similar to Java's final variables, so as far as I understand from what you're asking, the only way to assign new values in parallel to vals is by:

scala> val (x, y) = (1, 2);

or

scala> val s = (3, 4);
s: (Int, Int) = (3,4)

scala> s._1
res1: Int = 3

scala> s._2
res2: Int = 4
