Q.  How can I iterate through an ArrayList in Scala?

A.  If you have a legacy Java function that returns an ArrayList<>
you can iterate this way:

import collection.JavaConversions._ for (str <- asScalaBuffer(OldCode.oldFunction())) { System.out.println(str); }
OldCode.oldFunction() is your legacy function. asScalaBuffer() converts your ArrayList. It can be an ArrayList of anything.
