For looping

[jurka]

As there are lot of different ways to use the for loop compared to Java. Ill try to post my own examples and the book examples.

Simple Java's for-each could be in Scala

Code

GeSHi (java):
scala> val list = 12 :: 32 :: 4 :: 4 :: Nil
list: List[Int] = List(12, 32, 4, 4)
 
scala> for (i <- list) println(i)
 
Created by GeSHI 1.0.7.20

Result :
12
32
4
4

You can filter the results

Code

GeSHi (java):
scala> for (i <- list; if i < 5) println(i)
 
Created by GeSHI 1.0.7.20

Result:
4
4
