Any reason for having "val capacity : Int" instead of "val Int Capacity" in Scala

Question

I am reading Scala and I am wondering ...
Why

val capacity : Int 

instead of

val Int capacity.

Any reason why this choice was made. If not, it does not seem to me like a good choice to move away from the Java way of declaring it. Would have made the transition from Java to Scala easier (not by much, but little bit)

Answer 1

Because the majority of the time you can leave off the Int part. Scala has a much neater system of type inference than Java does.

Answer 2

I think I read a statement by Martin Odersky himself somewhere saying that this decision was also made in order to improve readability. This is certainly the case, e.g. compare

val Double number = ...
val Array[(Seq[String], Map[Seq[String], Double])] something = ...
val String pattern = ...

with

val number : Double = ...
val something : Array[(Seq[String], Map[Seq[String], Double])] = ...
val pattern : String = ...

Most of the time you need to find names of references/mathods fast (visually), not types.
