What is the means to convert the following java String[] to a Scala List?
val trimmedList : List[String] = str.split("\\n")).map (_.trim) // Missing some code here, does not compile

For simplicity, use toList:
val trimmedList: List[String] = str.split("\\n").map(_.trim).toList
For complexity, use breakOut (which avoids creating an intermediate collection from map):
import collection.breakOut
val trimmedList: List[String] = str.split("\\n").map(_.trim)(breakOut)

thx. The actual problem is that I had two right parentheses after the split (take a look..) . I have not become accustomed to IJ's parser error reporting and tend to misinterpret. The "toList" was trivial at that point.
