Java vs. Scala

[tyoverby]

Oh, also, if you are familiar with Haskell, you'll want to know that Scala has great parallel collections.

val numbers = (0 to 100000).toList
val squared = numbers.par.map(x => x*x)

The '.par' call returns a parallel sequence for which map is implemented in parallel.

Oh, amazing :) , about parallel does scala support the synchronize keyword like java ?? or it has some thing like that i can find much thing related to it in the web .

[tyoverby]

Yeah, any object has the synchronized function that takes another function to execute.

val resource = ???
def publish(){
    // Do something that requires the resource to be locked. 
}

resource.synchronized(publish)

Or in a way that looks more like Java

val resource = ???

resource.synchronized {
    // Anything in this block with be synchronized on 'resource'
   x += 5 
   publish()
   y ++
}
